Abstract: The thalamus is primarily known as a relay for sensory information; however, it also critically contributes to higher-order cortical processing and coordination. Thalamocortical hyperconnectivity is associated with hallucinatory phenomena that occur in various psychopathologies (e.g., psychosis, migraine aura) and altered states of consciousness (ASC, e.g., induced by psychedelic drugs). However, the exact functional contribution of thalamocortical hyperconnectivity in forming hallucinatory experiences is unclear. Flicker light stimulation (FLS) can be used as an experimental tool to induce transient visual hallucinatory phenomena in healthy participants. Here, we use FLS in combination with fMRI to test how FLS modulates thalamocortical connectivity between specific thalamic nuclei and visual areas. We show that FLS induces thalamocortical hyperconnectivity between LGN, early visual areas and proximal upstream areas of ventral and dorsal visual streams (e.g., hV4, VO1, V3a). Further, an exploratory analysis indicates specific higher-order thalamic nuclei, such as anterior and mediodorsal nuclei, to be strongly affected by FLS. Here, the connectivity changes to upstream cortical visual areas directly reflect a frequency-dependent increase in experienced visual phenomena. Together these findings contribute to the identification of specific thalamocortical interactions in the emergence of visual hallucinations. Copy rights belong to original authors.

Abstract: The classes of retinal ganglion cells (RGCs) receive different combinations of L, M, and S cone inputs and give rise to one achromatic and two chromatic post-receptoral channels. Beyond the retina, RGC outputs are subject to filtering and normalization along the geniculo-striate pathway, ultimately producing the properties of human vision. The goal of the current study was to determine temporal sensitivity across the three post-receptoral channels in subcortical and cortical regions involved in vision, to better characterize post-retinal temporal processing. We measured functional magnetic resonance imaging (MRI) responses at 7 Tesla from participants viewing a high-contrast, flickering, spatially-uniform wide (~140 degree) field. Stimulus flicker frequency varied logarithmically between 2 and 64 Hz and targeted the L+M+S, L-M, and S-[L+M] cone combinations. These measurements were used to create temporal sensitivity functions (TSFs) of primary visual cortex (V1) across eccentricity, and spatially averaged responses from lateral geniculate nucleus (LGN), V2/V3, hV4, and MT. Functional MRI responses reflected known properties of the visual system, including higher peak temporal sensitivity to achromatic vs. chromatic stimuli, and low-pass filtering between the LGN and V1. V1 had the slowest peak temporal sensitivity across cortical regions, which increased at higher levels of the visual cortical hierarchy. Unexpectedly, peak temporal sensitivity decreased at greater eccentricities in area V1, especially for achromatic stimuli. Comparison of measured cortical responses to a model of integrated retinal output to our stimuli demonstrates that extensive filtering and amplification is applied to post-retinal signals.

Abstract: Conscious perception alternates between the two eyes' images during binocular rivalry. How hierarchical processes in our brain interact to resolve visual competition remains unclear. Here we investigated mesoscale neural circuitry of binocular rivalry in human cortical and subcortical areas using high-resolution functional MRI at 7 Tesla. Eye-specific rivalry modulation was strongest in the superficial layers of V1 ocular dominance columns (ODCs), and more synchronized in the superficial and deep layers. The intraparietal sulcus (IPS) generated stronger eye-specific modulation and increased feedback connectivity to the early visual cortex during binocular rivalry compared to stimulus replay. Although there was no evidence of eye-specific rivalry modulation in the lateral geniculate nucleus (LGN) of the thalamus, strong perceptual rivalry modulation can be found in its parvocellular (P) subdivision. Finally, IPS and ventral pulvinar showed robust perceptual rivalry modulation and increased connectivity to the early visual cortex. These findings demonstrate that local interocular competition arises from lateral mutual inhibition between V1 ODCs, and feedback signals from IPS to visual cortex and visual thalamus further resolve and synchronize visual competitions to generate conscious perception.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.01.11.523655v1?rss=1 Authors: Rowe, E., Zhang, Y., Garrido, M. Abstract: Conscious visual motion information follows a cortical pathway from the retina to the lateral geniculate nucleus (LGN) and on to the primary visual cortex (V1) before arriving at the middle temporal visual area (MT/V5). Alternative subcortical pathways that bypass V1 are thought to convey unconscious visual information. One flows from the retina to the pulvinar (PUL) and on to MT; while the other directly connects the LGN to MT. Evidence for these pathways comes from non-human primates and modest-sized studies in humans with brain lesions. Thus, the aim of the current study was to reconstruct these pathways in a large sample of neurotypical individuals and to determine the degree to which these pathways are myelinated, suggesting information flow is rapid. We used the publicly available 7T (N = 98; 'discovery') and 3T (N = 381; 'validation') diffusion MRI datasets from the Human Connectome Project to reconstruct the PUL-MT and LGN-MT pathways. We found more fibre tracts with greater density in the left hemisphere. Although the left PUL-MT path was denser, the bilateral LGN-MT tracts were more heavily myelinated, suggesting faster signal transduction. We suggest that this apparent discrepancy may be due to 'adaptive myelination' caused by more frequent use of the LGN-MT pathway that leads to greater myelination and faster overall signal transmission.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.01.04.522738v1?rss=1 Authors: Schneider, M., Tzanou, A., Uran, C., Vinck, M. Abstract: Rhythmic flicker stimulation has gained interest as a treatment for neurodegenerative diseases and a method for frequency tagging neural activity in human EEG/MEG recordings. Yet, little is known about the way in which flicker-induced synchronization propagates across cortical levels and impacts different cell types. Here, we used Neuropixels to simultaneously record from LGN, V1, and CA1 while presenting visual flicker stimuli at different frequencies. LGN neurons showed strong phase locking up to 40Hz, whereas phase locking was substantially weaker in V1 units and absent in CA1 units. Laminar analyses revealed an attenuation of phase locking at 40Hz for each processing stage, with substantially weaker phase locking in the superficial layers of V1. Gamma-rhythmic flicker predominantly entrained fast-spiking interneurons. Optotagging experiments showed that these neurons correspond to either PV+ or narrow-waveform Sst+ neurons. A computational model could explain the observed differences in phase locking based on the neurons' capacitative low-pass filtering properties. In summary, the propagation of synchronized activity and its effect on distinct cell types strongly depend on its frequency. Copy rights belong to original authors.

Abstract: The lateral geniculate nucleus (LGN), a retinotopic relay center where visual inputs from the retina are processed and relayed to the visual cortex, has been proposed as a potential target for artificial vision. At present, it is unknown whether optogenetic LGN stimulation is sufficient to elicit behaviorally relevant percepts and the properties of LGN neural responses relevant for artificial vision have not been thoroughly characterized. Here, we demonstrate that tree shrews pretrained on a visual detection task can detect optogenetic LGN activation using an AAV2-CamKII-ChR2 construct and readily generalize from visual to optogenetic detection. We also characterize how amplitude and frequency of optogenetic stimulation affect behavioral performance. Given the importance of temporal stimulation parameters, we also study tree shrew behavioral ability to discriminate among pairs of visual flicker frequencies and demonstrate performance transfer among related discrimination problems as well as limitations. Neural recordings in LGN and primary visual cortex (V1) examining two flicker discriminations reveal that while LGN neurons multiplex information about temporal stimulation discriminations, V1 neurons explicitly encode information about one or the other discriminations but not both. Our findings confirm the LGN as a potential target for visual prosthetics and introduce a distinction in stimulus encoding between thalamic and cortical representations that could be of fundamental importance in artificial vision.

Abstract: Segmenting the magnocellular (M) and parvocellular (P) divisions of the human lateral geniculate nucleus (LGN) has been challenging yet remains an important goal because the LGN is the only place in the brain where these two information streams are spatially disjoint and can be studied independently. Previous research used the amplitude of responses to different types of stimuli to separate M and P regions (Denison et al., 2014; Zhang et al., 2015). However, this method is confounded because the hilum region of the LGN exhibits greater response amplitudes to all stimuli and can be mistaken for the M subdivision (DeSimone & Schneider, 2019). Therefore, we have employed two independent methodologies that do not rely upon the functional response properties of the M and P neurons to segment the M and P regions: 1. structural quantitative MRI (qMRI) at 3T to measure the T1 relaxation time, and 2. monocular and dichoptic functional MRI (fMRI) procedures to measure eye-specific responses. Our qMRI results agreed with the anatomical expectations, identifying M regions on the ventromedial surface of the LGN. The monocular fMRI procedure was better than the dichoptic condition to identify the eye-dominance signals. Both procedures revealed significant right eye bias, and neither could reliably identify the first M layer of the LGN. These findings indicated that the qMRI methods are promising whereas the functional identification of contralateral layers requires further refinement. Copy rights belong to original authors.

Abstract: Developmental dyslexia (DD) is a reading disorder with a prevalence of 5-10%. Neuroscientific research has typically focused on explaining DD symptoms based on pathophysiological changes in the cerebral cortex. However, DD might also be associated with alterations in sensory thalami - central subcortical stations of sensory pathways. A post-mortem study on the visual sensory thalamus (lateral geniculate nucleus, LGN) showed histopathological changes in the magnocellular (M-LGN), but not in the parvocellular (P-LGN), subdivisions. M-LGN and P-LGN have different functional properties and belong to two different visual systems. Whether M-LGN alterations also exist in DD in-vivo is unclear. Also, the potential relevance of M-LGN alterations to DD symptoms is unknown. This lack of knowledge is partly due to considerable technical challenges in investigating LGN subdivisions non-invasively in humans. Here, we employed recent advances in high-field 7 Tesla functional magnetic resonance imaging (fMRI) to map the M- and P-LGN in-vivo in DD adults (n=26) and matched controls (n=28). We show that (i) M-LGN responses differ between DD and control participants, (ii) these differences are more pronounced in male than in female DD participants, and (iii) M-LGN alterations predict a core symptom of DD in male DD participants only, i.e., rapid naming ability. Our results provide a first functional interpretation of M-LGN changes in DD and support DD theories that propose a direct relevance of sensory thalamus alterations for DD symptoms. In addition, the sex-specific behavioral relevance of M-LGN alterations within DD calls for taking sex differences into account when planning brain-based therapeutic interventions.

Nga nhường thị trường năng lượng châu Âu lại cho Mỹ. Nhờ có khí hóa lỏng LNG/GNL, Qatar trở thành tâm điểm trong chính sách năng lượng của Liên Âu. Trung Quốc đi buôn có lãi khi mua vào khí đốt của Nga với giá rẻ, bán lại cho châu Âu theo thời giá thị trường. Đó là ba thay đổi lớn trên bàn cờ năng lượng thế giới vì chiến tranh Ukraina. Thủ tướng Đức Olaf Scholz thở phào nhẹ nhõm, kể từ đầu tháng 12/2022 tập đoàn dầu khí Adnoc của Các Tiểu Vương Quốc Ả Rập Thống Nhất bắt đầu xuất khẩu khí hóa lỏng LNG (GNL theo tiếng Pháp) cho Berlin. Thỏa thuận vừa đạt được sau vòng công du ba nước trong vùng Vịnh (24-25/09/2022) của thủ tướng Đức, giảm bớt áp lực với chính phủ. Cũng trong lĩnh vực này, cuối tuần qua tập đoàn dầu khí Pháp TotalEnergies thông báo đầu tư thêm 1,5 tỷ đô la để cùng khai thác mỏ North Field South với QatarEnergy. TotalEnergies trước đây đã đầu tư 2 tỷ đô la vào Qatar trong dự án North Field East. Đến 2026 North Field East bắt đầu cung cấp LNG cho châu Âu. Trên bản đồ thế giới, Qatar cùng với Hoa Kỳ và Úc là ba nhà cung cấp LNG quan trọng nhất. Cho đến rất gần đây, khách hàng chính của ba nguồn cung cấp này là châu Á, chính xác hơn và theo thứ tự là Nhật Bản, Hàn Quốc và Trung Quốc. Châu Âu cho đến tháng 2/2022 đã đánh cuộc vào dầu hỏa và khí đốt của Nga, ít quan tâm đến khí hóa lỏng. Vào lúc Matxcơva đưa quân sang Ukraina, 55 % khí đốt của Đức do một mình nước Nga cung cấp. Mặc dù ban hành lệnh trừng phạt Nga. Mãi đến cuối tháng 7/2022 Nga vẫn đảm bảo 1/3 năng lượng cho cỗ máy công nghiệp lớn nhất của Liên Âu. Ẩn số Trung Quốc Nga càng lúc càng khóa chặt các đường ống dẫn dầu vào khí đốt vào châu Âu, đặt toàn khối trước nguy cơ thiếu điện vào mùa đông này. Thị trường khí tự nhiên hóa lỏng « căng » thêm nữa vào lúc Hàn Quốc, khách hàng lớn thứ hai trên thế giới phải đong đầy 90 % kho dự trữ từ nay đến cuối tháng 10/2022. Nhật lo xa đã đạt chỉ tiêu từ lâu nay. Riêng với Trung Quốc, nhu cầu về LNG của nước này vẫn còn là một ẩn số : Liên Âu chưa biết có phải cạnh tranh với Trung Quốc để tranh giành LNG của các nhà cung cấp hay không. Trước mắt, câu trả lời có lẽ là không. Thứ nhất, hiện tại Trung Quốc đang dễ dàng mua dầu hỏa và khí đốt của Nga. Thứ hai, do tác động từ các đợt phong tỏa liên tiếp, các nhà máy tại Hoa Lục phải đóng cửa, nhu cầu tiêu thụ năng lượng tại « công xưởng » của thế giới này có khuynh hướng sụt giảm. Thứ ba nữa là Trung Quốc vẫn thiên về than đá, một giải pháp tuy gây ô nhiễm, thải nhiều CO2 nhưng rẻ hơn cho các nhà sản xuất. Ba yếu tố này cộng lại đã cho phép Trung Quốc dễ dàng « nhường » những các hợp đồng LGN của mình với Nga lại cho châu Âu. Báo tài chính Nhật Nikkei đầu tháng 9/2022 châm biếm gọi Trung Quốc là vị « cứu tinh » của Liên Âu : 45 tàu chở LNG của tập đoàn SINOPEC đã chuyển hướng trực chỉ châu Âu thay vì đi tiếp về Hoa Lục. Trong tám tháng đầu 2022, Trung Quốc đã bán lại cho các đối tác châu Âu khoảng 3 triệu tấn khí hóa lỏng, và nhờ vậy mà đã « lãi gấp đôi, thậm chí là gấp ba » so với giá hợp đồng khi mua vào của LNG của Nga. Nhà báo của Le Monde và cũng là một chuyên gia về bản đồ, về địa lý Delphine Papin ghi nhận : « Trên thế giới hiện nay có 640 tàu chở khí hóa lỏng, đó là những loại tàu đặc biệt với bồn chứa lớn, có cách nhiệt. Qua hệ thống theo dõi và định vị sử dụng trong ngành giao thông vận tải đường biển, người ta thấy càng lúc càng có nhiều tàu đang di chuyển về châu Á đã đột ngột đổi hướng, trực chỉ châu Âu ». Khủng hoảng năng lượng châu Âu : Mỹ thắng lớn Từ đầu cuộc xung đột Nga-Ukraina các tàu chở khí LNG tấp nập qua lại giữa hai bờ Đại Tây Dương : Liên Hiệp châu Âu nhập khẩu thêm 60 % khí hóa lỏng của Mỹ, trong khi đó thị phần khí đốt của Nga tại châu Âu đang từ 40-45 % trước chiến tranh Ukraina đã rơi xuống còn 9 % theo lời chủ tịch Ủy Ban châu Âu, Ursula von der Leyen. Điều đó không cấm cản hóa đơn thanh toán năng lượng của Liên Âu cho các nhà cung cấp Nga tăng vọt : trong 9 tháng đầu năm nay, bất chấp lệnh cấm vận, Liên Âu đã rót 158 tỷ đô la vào các tập đoàn dầu khí của Nga. Để bù đắp vào khoảng trống hơn 155 tỷ mét khối khí đốt của Nga một năm, Liên Âu đã đánh cược vào khí đốt của Hoa Kỳ. Từ 2016 nhờ công nghệ khai thác dầu, khí đá phiến, Mỹ đã nhanh chóng trở thành một nhà cung cấp lớn của thế giới. Trong lĩnh vực LNG, Mỹ thậm chí đã qua mặt cả Qatar. Vào lúc Nga dùng năng lượng như một loại vũ khí để bắt chẹt châu Âu, khóa các đường ống sang Đức, giảm nguồn cung cấp cho Ý, ngừng cung cấp cho Ba Lan và Bulgari thì tổng kinh ngạch xuất khẩu khí hóa lỏng của Mỹ vào Liên Âu đã được nhân lên gấp đôi : trong 6 tháng đầu năm, Liên Âu nhập khẩu 27 triệu tấn LNG của Mỹ thay vì 21 triệu tấn cho cả năm 2021. Trong cùng thời gian này, số lượng tàu chở khí hóa lỏng từ Mỹ đã cập các bến cảng châu Âu cao hơn nhiều so với khoảng 230 lượt trong cả năm 2021. Thống kê của bộ Thương Mại Mỹ cho thấy 70 % xuất khẩu LNG trong năm 2022 dành để bán sang châu Âu thay vì 30 % như năm ngoái. Trên thị trường châu Âu, Hoa Kỳ là nguồn cung cấp đến gần một nửa nhu cầu tiêu thụ khí hóa lỏng. Chính quyền Biden mùa xuân vừa qua cam kết cung cấp đến 50 tỷ mét khối khí hóa lỏng một năm cho các « đồng minh châu Âu » và có khả năng « giúp đỡ » Bruxelles thêm 20 tỷ mét khối nữa nếu như Liên Âu chịu « trả giá » theo luật cung cầu ! Qatar về thứ nhì như bị bỏ xa lại phía sau với 15 % - Nga trước mắt vẫn đứng thứ ba với 14 % theo số liệu của eurostat (tháng 6/2022) Thierry BROS giáo sư trường Khoa Học Chính Trị Paris, Sciences Po phân tích : « Châu Âu trông cậy nhiều vào Qatar và Mỹ là hai nhà sản xuất khí hóa lỏng tương đối rẻ. Giá thành của Úc đắt hơn. Châu Âu để giảm bớt lệ thuộc vào năng lượng của Nga hướng về các nhà cung cấp tương đối gần với mình về mặt địa lý hoặc là gần gũi về chí hướng. Trong bài toàn này, đương nhiên Liên Âu hướng tới Qatar và Hoa Kỳ ». Qatar ông khổng lồ sắp vươn vai thức dậy Với chiến tranh Ukraina, Doha trở thành điểm hẹn của hầu hết các lãnh đạo châu Âu. Với diện tích chưa đầy 12.000 km vuông và với 2,8 triệu dân này, Qatar là một mỏ khí đốt của thế giới, hiện đứng hạng tư trong số các nhà cung cấp khí đốt, nhưng riêng trong lĩnh vực khí hóa lỏng, thì « cậu bé tí hon » này dám đọ sức ngang ngửa với ông khổng lồ Mỹ và đã có những bước chuẩn bị để chiếm thị phần của Nga. Theo thẩm định của giới trong ngành, 50 % tiềm năng cung cấp LNG cho thế giới đang do Qatar và Mỹ nắm giữ. Do Nga xâm chiếm Ukraina, thị phần của Qatar tại châu Âu đã tăng lên gấp đôi đang từ hơn 7 % nhảy vọt lên thành 15 %. Để chuẩn bị thống lĩnh thị trường LNG thế giới, từ nhiều năm qua, Doha đã đẩy mạnh đầu tư với mục đích nâng khả năng cung cấp lên thêm 60 % vào ngưỡng 2027. Có nghĩa là trong từ 4 đến 5 năm nữa, hàng năm Qatar sẽ cung cấp 110 triệu tấn khí hóa lỏng cho thế giới thay vì 77 triệu tấn như hiện tại. Để đạt được mục tiêu này, Qatar đã huy động các tập đoàn quốc tế như TotalEnergies, Shell, Eni, ExxonMobil và ConocoPhillips để xây dựng nhà máy khí hóa lỏng lớn nhất thế giới. Hiện đang làm chủ 67 tàu chở dầu LNG, Doha đã ký hợp đồng, chủ yếu là với tập đoàn đóng tàu Hàn Quốc, để trang bị thêm 100 chiếc nữa trong 5 năm sắp tới. Chuyên gia về năng lượng, giáo sư Thierry Bros, trường Khoa Học Chính Trị Paris, dù vậy thận trọng nhắc lại với 110 triệu tấn khí hóa lỏng Qatar sẽ cung cấp cho thế giới hàng năm, khối lượng đó tương đương với 50 % khí đốt của Nga tiêu thụ trong toàn khối Liên Âu. Trong cuộc họp báo cuối tuần qua thủ tướng kiêm bộ trưởng Năng Lượng Qatar, Saad Sherida Al-Kaabi khẳng định một khi các cơ sở mới bắt đầu hoạt động Doha dành từ 40 đến 50 % sản lượng để cung cấp cho châu Âu. LNG chưa giải quyết được vấn đề thiếu năng lượng cho châu Âu Đành rằng Liên Hiệp châu Âu đang lao vào cuộc săn lùng LNG, đôn đáo liên hệ với một số nước Trung Á, sưởi ấm quan hệ với một số nhà sản xuất ở châu Phi như Algérie… thậm chí quan tâm đến cả khí hóa lỏng của Malaysia, Indonesia, hai nguồn cung cấp tại Đông Nam Á, nhưng để « cai nghiện » khí đốt nói chung của Nga thì « đường còn dài ». Michael Stoppard thuộc cơ quan thẩm định tài chính Standard&Poor's đánh giá : « LNG là giải pháp duy nhất và sẽ làm đảo lộn trật tự trên thị trường năng lượng toàn cầu trong thập niên sắp tới, nhưng hiện tại sản lượng khí hóa lỏng của thế giới chưa đủ để đáp ứng nhu cầu tiêu thụ cho thị trường châu Âu ». Nói cách khác trước mắt tình hình vẫn sẽ « rất căng thẳng trong từ 3 đến 4 năm sắp tới » vì nhiều lý do. Trước hết như vừa trình bày, Qatar tuy có tiềm năng rất lớn nhưng khách hàng phải kiên nhẫn thêm ít nhất là cho đến khoảng 2025/2026 khi mà những nhà máy mới bắt đầu đi vào hoạt động. Nhìn sang Hoa Kỳ, đúng là tổng thống Biden đã cam kết bán LNG cho các đồng minh châu Âu, nhưng đó là một tuyên bố mang tính chính trị. Trong lúc tại Hoa Kỳ, công nghiệp dầu khí do tư nhân kiểm soát và chỉ có một vài đại tập đoàn mới có tiếng nói sau cùng. Nhìn đến khả năng cung cấp LNG trên thế giới, Qatar hay Mỹ, và kể cả Úc nếu muốn bán thêm cho châu Âu, thì cần phải có thêm những nhà máy nén khí. Hiện tại 7 nhà máy tại Hoa Kỳ đã hoạt động ở mức gần như tối đa. Ở đầu này của thị trường, để LNG thay thế khí đốt của Nga mà từ trước đến nay được chuyển vào Liên Âu qua các đường ống pipelines, thì châu Âu cần xây dựng thêm các bến tiếp nhận tàu chở khí hóa lỏng, cần có thêm kho chứa LNG, có thêm các trạm tái khí hóa. Hiện tại trên toàn châu lục, có khoảng 30 trạm tiếp nhận LNG đang hoạt động với công khoảng 70 % công suất. Từ khi chuyển hướng sang sử dụng khí hóa lỏng, Pháp và nhất là Đức thông báo xây dựng thêm các bến tiếp nhận LNG : Pháp mở thêm một trạm thứ năm tại cảng biển Le Havre, Đức dự trù thêm 4 cơ sở, một ở Hà Lan và hai tại Ý… Tất cả những công trình đó đòi hỏi thời gian, vào lúc mà chỉ một vài tuần lễ nữa châu Âu bước vào mùa đông. Những hợp đồng tập đoàn TotalEnergies vừa ký được với Qatar tuy đầy hứa hẹn nhưng trong ngắn hạn chưa thể tháo gỡ bế tắc về năng lượng cho nước Pháp. Hợp đồng của Đức mua khí hóa lỏng của Các Tiểu Vương Quốc Ả Rập Thống Nhất quá khiêm tốn để có thể thay thế khối lượng mà đường ống Nord Stream 1 vẫn cung cấp cho Berlin từ trước tới nay. Điều hiển nhiên nhất là qua việc đưa quân xâm chiếm Ukraina, tổng thống Vladimir Putin đã đẩy khách hàng lớn nhất của các tập đoàn năng lượng Nga vào vòng tay Hoa Kỳ. Vô tình hay cố ý, Matxcơva đã tạo cơ hội cho Qatar nhanh chóng trở thành tâm điểm trên một bàn cờ mang tính chiến lược. Về phần châu Âu, trước mắt vẫn lo thiếu điện trong mùa đông sắp tới. Trong tương lai, nếu không còn lệ thuộc vào Nga về dầu khí, thì Liên Hiệp châu Âu sẽ lệ thuộc vào Mỹ, vào các đối tác ở Trung Đông, tiêu biểu nhất là Qatar. Trong điều kiện đó, các tổ chức nhân quyền kêu gọi tẩy chay Cúp bóng đá Thế Giới 2022 sắp mở ra tại vào tháng 11/2022, phản đối Doha bóc lột lao động, cho sự kiện thể thao này sẽ là « công dã tràng » !

Abstract: The mechanism or microcircuitry behind orientation selectivity in primary visual cortex (V1), and the means by which it develops without supervision or visual input, both remain unresolved questions. Work on the developmental question has assumed the prevalent spatial convergence model of orientation selectivity as the target mechanism. Encouraged by growing evidence challenging both the completeness of this model and its developmental viability, we investigated an alternative scheme. Accordingly, we demonstrate computationally how a scheme in which orientation selectivity originates from the orientation biases already in the retina and lateral geniculate nucelus (LGN) can answer both the mechanistic and developmental questions. In this scheme, the divergence of outputs from the retina allows retinal spontaneous activity to create correlations within the LGN. These correlations in turn allow a Hebbian plasticity mechanism to strengthen those LGN inputs to V1 which carry similar orientation biases and thus provide an orientation tuned excitatory input.

Abstract: In natural scenes, there is substantial variation in the mean and variance of light levels (luminance and contrast). Retinal ganglion cells maintain their sensitivity despite this variation and their limited signaling bandwidth using two adaptive mechanisms, which control luminance and contrast gain. However, the signature of each mechanism and their interactions further downstream of the retina are unknown. We recorded neurons in the magnocellular and parvocellular layers of the lateral geniculate nucleus (LGN) in anesthetized adult male macaques and characterized how they adapt to changes in contrast and luminance. As contrast increases, neurons in the magnocellular layers maintain sensitivity to high temporal frequency stimuli but attenuate sensitivity to low temporal-frequency stimuli. Neurons in the parvocellular layers do not adapt to changes in contrast. As luminance increases, magnocellular and parvocellular cells increase their sensitivity to high temporal frequency stimuli. Adaptation to luminance is independent of adaptation to contrast, as previously reported for LGN neurons in the cat. Our results are similar to those previously reported for macaque retinal ganglion cells, suggesting that adaptation to luminance and contrast result from two independent mechanisms that are retinal in origin.

While Curt is more of a Kettlebell, Speed Cord guy, I fancy myself as a suspension trainer and landmine fella.We're covering a lot of ground on this one. So enjoy and let us know what you would need in a home gym.
When LGN opened in 2011, it was a CrossFit affiliate. Shortly after its first year, the CrossFit name was replaced with "Performance." Shortly after that, the affiliate status was dropped.It's not a path for everyone or every gym. But, it allowed LGN to grow its membership numbers, retention numbers, coaches and instilled pride and ownership in the product.If you love CrossFit, it's still OK to like this episode.If someone you know should hear it for one reason or another, please spread it around. I'd love to continue to grow the audience and the 4th Shift.Talk to you soon.
Today we're talking … to Peter Russell.Peter Russell is a leading thinker on consciousness and contemporary spirituality. He is the author of a dozen books, including The Global Brain, Waking Up in Time and From Science to God. His new book, Letting Go of Nothing, was published this August. As a side note I read this book over the past week and I have to say it's a gem. There's so much treasure It…in bite size chunks, ideal for people with short attention spans like myself.Peter studied theoretical physics, experimental psychology, and computer science at the University of Cambridge, and meditation and Eastern Philosophy in India. And pioneered the introduction of personal growth programs to corporations in the 1980s. He's also famous for predicting the coming of something called the Internet way back in the 80s in the aforementioned book Global Brain.He's a renowned teacher of meditation, and he's kindly agreed to lead a short meditation for us during the podcast.His mission is to distill the essential wisdom on human consciousness found in the world's various spiritual traditions, and to disseminate their teachings on self-liberation in contemporary and compelling ways. https://www.peterrussell.com/LGN/book/index.php
Hemos hablado de casi todos los elementos esenciales para una banda, y no podríamos dejar de lado al único instrumento que el ser humano tiene incluido y que no requiere de conectarse ningún dispositivo externo para escucharlo, nos referimos a la voz y desde luego al complemento indispensable: la presencia. Porque nunca es suficiente tener una excelente voz, es absolutamente mandatorio tener la personalidad que detone la conexión con la gente, y que atraiga la atención de las masas. Acá hablamos de los Frontmans favoritos de LGN, personajes al frente de las bandas que son fundamentales en la historia del hard rock y el metal.
Si bien es cierto que hemos hablado sobre lo icónico que puede resultar la imagen de una guitarra en el metal y como a los largo de todas estas décadas permanece con el símbolo mas representativo de nuestra escena, es momento de abrir paso al instrumento que sin lugar a dudas es el que marca el tempo y el que le pone el grado de agresividad a los tracks, que tan rápido o que tal lento puede sonar un track depende en gran medida de las baterías. Acá hablamos de los baterías favoritos de LGN y el legado que ha dejado en nosotros como músicos.
En la música, el instrumento de las 4 cuerdas (por lo general) es el elemento del que muchas veces no se habla a profundidad. Y es que en no es fácil apreciar aquello de pronto no se escucha o no se distingue, pero que definitivamente envuelve, da profundidad, volumen, y cuerpo a la música. Acá en LGN hablamos del bajo, artefacto que es fundamental en nuestro amado genero, y que es algunas veces subestimado. En este capítulo nos damos el tiempo para honrar y hablar de nuestros bajistas favoritos, de las leyendas, pero también de la sangre fresca, de aquellos que hacen retumbar los recintos cuando de directos se trata.
Podcast: This week on the show, we present a pre-recorded conversation with author, Peter Russell, about his latest book, Letting Go of Nothing: Relax Your Mind and Discover the Wonder of Your True Nature (An Eckhart Tolle Edition). Peter Russell is an author, speaker, and leading thinker on consciousness and contemporary spirituality. He believes the critical challenge today is freeing human thinking from the limited beliefs and attitudes that lie behind many of our problems — personal, social, and global. His mission is to distill the essential wisdom on human consciousness found in the world's various spiritual traditions and to disseminate it in contemporary and compelling ways. Russell earned a first-class honors degree in theoretical physics and psychology — as well as a master's degree in computer science — at the University of Cambridge, England. He also studied meditation and Eastern philosophy in India. He coined the term global brain with his 1980s bestseller by the same name in which he predicted the internet and the impact it would have on humanity. He is the author of twelve books including Waking Up in Time and From Science to God. More information about Peter Russell's work can be found at: Peter Russell's Website: www.peterrussell.com, Letting Go of Nothing page: Letting Go of Nothing, Online course on Meditation: How to Meditate - Without Even Trying.
In this episode I had to let off on a number of different topics, from Mother's Day down to the whole "Porscha Williams" situation...TUNE IN to hear my thoughts on some of todays current events, and just an overall check in with my LGN family!

As more and more businesses experience latency issues in traditional cloud databases, edge computing is now more popular than ever before. Having a device at the edge of your network allows for smoother run times while also synchronising with other geo-distributed devices in your ecosystem that are placed on other parts of the globe. Fusing an already impressive piece of kit with machine learning results in something truly impressive: Edge AI. Edge AI brings in faster decision making, vast improvements to UX and is more energy efficient than other data management tools. Processing data can now be done in real time, so why is there still scepticism about adopting edge AI? Why haven't more businesses adopted it already? Joining us in this EM360 podcast is Dan Warner, CEO and Co-Founder of LGN; an organisation dedicated to bringing new edge technology to a wider audience.

Hey monkiis, I just finished up a 5-week training program I had written for myself and wanted to share some reflections. I also wanted to share some solid thoughts shared by the NorCal Wildman monkii Craig. He shared a personal anecdote of his experience getting JACKED using bodyweight training only and also had a really solid hierarchy that he developed around the 'why' for his training. monkii Craig's Training hierarchy: 1. Joy (peace, contentment, equanimity, life balance/satisfaction) 2. Healthspan (time on this planet free from disability) 3. Lifespan (total time alive) 4. GPP (be reasonably good at any physical task life throws at me) 5. Vanity (esthetics, body comp, LGN, etc.) Thanks, monkii Craig! Overall, I was pretty psyched about my training program for the past 5-weeks. There are definitely some tweaks to be made, but overall I feel like I'm making progress. I'd like to try and really make Microworkouts a priority and sprinkle in focused training sessions on top of these. Here is a link to the episode I did about building this training plan back in January 2021. If you have questions, comments, or a potential guest suggestion please send a note to Elders@monkii.co or send us a DM to @monkii.co on Instagram. Let's keep the conversation going. Thanks for tuning in and if you are enjoying the episodes we would be eternally grateful if you could leave a 5-star review. It helps to grow the monkii family and spread the good word of the Wild. Thank you. See you out there and monkii on, -monkii Dan www.monkii.co

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.11.10.374611v1?rss=1 Authors: Seelke, A., Beckman, D., Bennett, J., Dougherty, P., Van Rompay, K. K. A., Keesler, R., Pesavento, P. A., Coffey, L. L., Morrison, J. H., Bliss-Moreau, E. Abstract: Zika virus (ZIKV) infection of pregnant women can cause major congenital neuronal abnormalities. In the present study, we evaluated neuropathological consequences of fetal ZIKV exposure in rhesus macaques, a highly translatable animal model for human neural development. Quantitative neuroanatomical analyses of the nearly full-term brains of fetuses infected with ZIKV at gestational days 50, 64, and 90, and three procedure-matched sham-inoculated controls were carried out. Whole tissue sections across a complete cerebral hemisphere were evaluated using immunohistochemical and neuroanatomical staining techniques to detect virus localization, identify affected cell types and evaluate gross neuroanatomical abnormalities. None of the subjects were microcephalic. Immunohistochemical staining revealed the presence of ZIKV in the frontal lobe, which contained activated microglia and showed increased apoptosis of immature neurons. ZIKV-infected animals exhibited macrostructural changes within the occipital lobe, including a reduction in gyrification as well as a higher proportion of white matter. Finally, the ZIKV-infected subjects had abnormalities throughout the visual pathway, including disorganization within the lateral geniculate nucleus (LGN) and primary visual cortex (V1). Regional differences tracked with the temporal patterns of the developing brain and likely reflect the neural progenitor cell tropism ZIKV exhibits, painting a picture of inflammatory processes related to viral infiltration sweeping through the cortex, followed by a wave of cell death resulting in morphological changes. These findings may help explain why some infants born with normal sized heads during the ZIKV epidemic manifest developmental challenges as they age, and ultimately may contribute to developing effective treatments and interventions.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.02.280024v1?rss=1 Authors: Just, N., Adriaensen, H., Chevillard, P.-M., Batailler, M., Dubois, J.-P., Migaud, M. Abstract: Biomedical investigations in clinically relevant animal models is of crucial interest for faster and appropriate transfer to human. The ovine model has already demonstrated its potential compared to rodents and non-human primates (NHP) in various studies: sheep possess a gyrencephalic brain, captivity is not an issue and can undergo magnetic resonance imaging (MRI) in routine clinical scanners (1.5T, 3T) under identical conditions using similar techniques to humans. To date, the effects of anesthesia have been poorly explored and only few functional MRI (fMRI) studies were conducted in sheep. Here, Blood Oxygen Level dependent fMRI and perfusion MRI were conducted in lambs and adult ewes at 3 T. Robust but weak BOLD responses to visual stimulation were found in the lateral geniculate nucleus (LGN) up to 3% isoflurane anaesthesia. BOLD responses were weaker in adult sheep than in lambs while relative cerebral blood volumes (rCBV) and relative cerebral blood flows (rCBF) were significantly higher in lambs than in adult sheep for both gray and white matter in accordance with previous findings in the human. Assessment of functional responses in healthy individuals under adequate physiological conditions is essential for robust translational studies. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.08.14.250779v1?rss=1 Authors: Mueller-Axt, C., Eichner, C., Rusch, H., Kauffmann, L., Bazin, P.-L., Anwander, A., Morawski, M., von Kriegstein, K. Abstract: The human lateral geniculate nucleus (LGN) of the visual thalamus is a key subcortical processing site for visual information analysis. A non-invasive assessment of the LGN and its functionally and microstructurally distinct magnocellular (M) and parvocellular (P) subdivisions in-vivo in humans is challenging, because of its small size and location deep inside the brain. Here we tested whether recent advances in high-field structural quantitative MRI (qMRI) can enable MR-based mapping of human LGN subdivisions. We employed ultra-high resolution 7 Tesla qMRI of a post-mortem human LGN specimen and high-resolution 7 Tesla in-vivo qMRI in a large participant sample. We found that a quantitative assessment of the LGN and a differentiation of its subdivisions was possible based on microstructure-informed MR-contrast alone. In both the post-mortem and in-vivo qMRI data, we identified two components of shorter and longer longitudinal relaxation time (T1) within the LGN that coincided with the known anatomical locations of a dorsal P and a ventral M subdivision, respectively. Through a subsequent ground truth histological examination of the same post-mortem LGN specimen, we showed that the observed T1 contrast pertains to cyto- and myeloarchitectonic differences between LGN subdivisions. These differences were based on cell and myelin density, but not on iron content. Our qMRI-based mapping strategy overcomes shortcomings of previous fMRI-based mapping approaches. It paves the way for an in-depth understanding of the function and microstructure of the LGN in humans. It also enables investigations into the selective contributions of LGN subdivisions to human behavior in health and disease. Copy rights belong to original authors. Visit the link for more info

Stemmen Siden 2007 har jeg undervist i non verbale signaler. Hver gang vi kommer til stemmen, kommer jeg altid lidt til kort. Og alligevel høre jeg mig selv sige: “Vi kan høre det på stemmen!” Men hvad er det vi kan høre … det er det vi går på opdagelse i, sammen med Kathrine K. Andersen Hvad er det vi kan høre? Hvordan virker stemmen? Hvilke “bogstaver” vi kan vi lytte efter? Hvilke stemme er den mest sexede? Hvordan tuner vi vores talestemme? Kan man høre løgn? Her i 2. episode, går jeg Pernille Slot, på opdagelse sammen med Kathrine K. Andersen i stemmen. Hvad er det vi kan lytte efter og hvordan kan vi tune vores eget instrument, stemmen.

Bør politikere ljuge? Eller er politikerne bundet av andre moralske forpliktelser og vurderinger enn oss "vanlig dødelige"? Denne uken ser SOSpodden nærmere på hvilken rolle løgn spiller i politikken. Vi lover! PS. På grunn av tekniske problemer er lyden litt lav i denne episoden. Vi beklager!
Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.05.18.101881v1?rss=1 Authors: Lian, Y., Almasi, A., Grayden, D. B., Kameneva, T., Burkitt, A. N., Meffin, H. Abstract: There are two distinct classes of cells in the primary visual cortex (V1): simple cells and complex cells. One defining feature of complex cells is their spatial phase invariance; they respond strongly to oriented grating stimuli with a preferred orientation but with a wide range of spatial phases. A classical model of complete spatial phase invariance in complex cells is the energy model, in which the responses are the sum of the squared outputs of two linear spatially phase-shifted filters. However, recent experimental studies have shown that complex cells have a diverse range of spatial phase invariance and only a subset can be characterized by the energy model. While several models have been proposed to explain how complex cells could learn to be selective to orientation but invariant to spatial phase, most existing models overlook many biologically important details. We propose a biologically plausible model for complex cells that learns to pool inputs from simple cells based on the presentation of natural scene stimuli. The model is a three-layer network with rate-based neurons that describes the activities of LGN cells (layer 1), V1 simple cells (layer 2), and V1 complex cells (layer 3). The first two layers implement a recently proposed simple cell model that is biologically plausible and accounts for many experimental phenomena. The neural dynamics of the complex cells is modeled as the integration of simple cells inputs along with response normalization. Connections between LGN and simple cells are learned using Hebbian and anti-Hebbian plasticity. Connections between simple and complex cells are learned using a modified version of the Bienenstock, Cooper, and Munro (BCM) rule. Our results demonstrate that the learning rule can describe a diversity of complex cells, similar to those observed experimentally. Copy rights belong to original authors.

"Roter oder gelber Slip? Und wie lange soll ich ihn tragen?" So oder so ähnlich hören sich wahrscheinlich Gespräche an, wenn man seine Unterwäsche verkauft. Ob an damit das große Geld machen kann? Leyla und Saskia diskutieren es aus. Außerdem unterhalten sie sich über Influencer, die mehr als fake sind und im echten Leben leider gar nicht so glamourös aussehen, wie auf Instagram. Heute widmen wir uns auch mal wieder ernsteren Themen, z.B. Organspende. Wir alle wissen wie wichtig es ist Leben zu retten und wenn man das nach dem Tos noch mit seinen Organen kann, warum sollte man das dann nicht machen? Wir rufen dazu auf Lebensretter zu werden und sich einen Organspendeausweis zuzulegen. Warum das so wichtig ist erfahrt ihr in dieser Folge undwarum besonders Saskia das Spenden von Organen wichtig ist erzählt sie hier und heute auch Wer mehr hören will abonniert uns und den Podcast auf allen gängigen Kanälen: Instagram: @letsgetnaked.podcast @datleylo @saskiahkn Spotify, Apple Podcasts, Anchor.fm, etc. Und wer eine Runde kuscheln will gibt LGN 5 Sterne!

"Happy Birthday to you! Happy Birthday to you!" Wir haben einen Special Guest und das an ihrem Geburtstag! Trotzdem ist diese Folge etwas ernster, mit persönlicheren Themen und viel nackter, als bisher. Wir beschäftigen uns mit dem Verhältnis zu unseren Vätern und unserer Zukunft, mit toxischen Beziehungen und Narzissten und haben trotz aller Ernsthaftigkeit der Themen hin und wieder einen Lacher parat. Den mit einem Lachen auf den Lippen, sind selbst die härtesten Themen irgendwie ertragbarer. Außerdem verrät Saskia, wie ihr Traumtyp aussehen müsste und was er mitbringen sollte. Also liebe heiratswillige Junggesellen da draußen, bewerbt euch gerne! Leyla gibt derweil preis unter welchen Umständen sie aufgewachsen ist. Und unser Special Guest harkt sich in die Themen ein und gibt noch mal eine ganz persönliche Sichtweise hinzu. Wer ehrliche und auch verletzliche Geschichten hören möchte, in denen sich der Ein oder Andere sicherlich wiederfinden kann, für den ist diese Folge gemacht! Wenn du durch eine harte Phase in deinem Leben gehst oder gegangen bist, wirst du dich hier auf jeden Fall verstanden füllen. The grass isn't always greener on the other side... Auch wenn es so aussieht. It's green, where you water it! Und deswegen sollte man bestimmte Dinge hinter sich lassen und das Leben einfach nehmen wie es kommt. Am Ende ist das Einzige, was du ändern kannst eh nur, wie du mit der Situation umgehst. Also let shit happen and move on. Immer positiv bleiben!

“IF YOU'RE NOT HUNGRY, DON'T EAT." Health is one of the most important things to me. If your body isn’t operating at 100% efficiency then your mind can’t either. A lot of this really does come down to diet. On a good diet, you will burn fat efficiently. You’ll have a healthier heart, your brain will function properly, and your body will be able to repair itself properly. This last part is huge for those who are recovering from surgery, or dealing with various diseases. Plus, there’s an added benefit on top of it all - you will lose weight and look great naked. Who doesn’t want that? To talk about the importance of a solid diet and how it can make a huge impact on your life overall, I brought back this clip from Mark Sisson.

The position of the mitotic spindle is controlled by the microtubule-based motor dynein and a ternary complex of the proteins NuMA, LGN, and Ga. Kotak et al. demonstrate that the ternary complex's primary function is to localize dynein to the cell cortex and that cortical dynein is sufficient to position the mitotic spindle in HeLa cells. This biosights episode presents the paper by Kotak et al. from the October 1, 2012, issue of The Journal of Cell Biology and includes an interview with author Pierre Gonczy (EPFL, Lausanne, Switzerland). Produced by Caitlin Sedwick and Ben Short. See the associated paper in JCB for details on the funding provided to support this original research.

Diese Arbeit präsentiert Ergebnisse an piezoelektrischen Materialien aus der Langasitfamilie, die unter extremen Bedingungen untersucht wurden. Die Einkristalle aus dieser Familie, vor allem La3Nb0.5Ga5.5O14 (LNG) und La3Ta0.5Ga5.5O14 (LTG), sind vielversprechende Materialien für Oberflächenwellen (OFW) –Substratmaterialien, die in der mobilen Kommunikationstechnik der Frequenzsteuerungsgeräte (mobile Kommunikation, Sensoren, usw.) und bei Hochtemperatur- OFW- Anwendung finden. Mit LNG und LTG OFW-Sensorelementen können physikalische Meßgrößen, wie Druck und Temperatur erfaßt werden. Aus diesem Grund sind die Strukturuntersuchungen an LNG und LTG bei verschiedenen Drucken und Temperaturen extrem wichtig. Die Struktur von LNG und LTG ist unter normalen Bedingungen trigonal mit der Raumgruppe P321. In der Struktur sind die schweren Atome polyedrisch von Sauerstoffatomen koordiniert. Vier Polyedertypen bilden decaedrisch-oktaedrische und tetraedrische Schichten. Diese sind in einer A-B- Stapelfolge senkrecht zur c-Achse angeordnet. Die Kristallstrukturen von LNG und LTG wurden mittels Röntgenstrukturanalyse an LNG- und LTG- Einkristallen in Hochdruck- Diamant -Stempel Zellen unter Druck bis 23GPa untersucht. Die Proben für diese Forschungsarbeit wurden von den Forschungsgruppen von B. V. Mill (Rußland) und J. Bohm (Deutschland) freundlicherweise zur Verfügung gestellt. Als druckübertragende Medien wurden Alkohol und Helium benutzt. a- Quarz Kristalle und die Rubinfluoreszenzmethode wurden zur Druckmessung herangezogen. Die Experimente mit Röntgenstrahlung wurden im eigenen Labor und am Hamburger Synchrotronstrahlungslabor (HASYLAB, Beamline D-3) durchgeführt. Die Gitterkonstanten und Reflexintensitäten von LNG und LTG wurden unter Drucken bis 22,8 beziehungsweise 16.7GPa gesammelt. Innerhalb des erforschten Druckbereichs nimmt das c/a- Verhältnis von 0,6232 bis 0,6503 für LNG und von 0,6227 bis 0,6350 für LTG zu. Folglich ist die a-Achse die an stärksten komprimierte Richtung in beiden Substanzen. Damit zeigen LNG und LTG unter Druck ein anisotropes Verhalten, das durch unterschiedliche Bindungsstärken in den Richtungen parallel zu den a- beziehungsweise c- Achsen bedingt ist. Unter hydrostatischem Druck ist die Komprimierung der c- Richtung (also zwischen den Schichten) steif, was wegen der weniger flexiblen Verknüpfung der Polyeder (gemeinsame Kanten) verständlich ist. Demgegenüber ist die Komprimierung innerhalb der ab- Ebene (also innerhalb der Schichten) größer und kann hauptsächlich durch die abnehmenden Volumina und Verzerrungen der Polyeder erreicht werden. Weil die Kristallstrukturen von LNG und LTG wegen der hohen Symmetrie und der Polyederkopplungen sehr steif sind, führt die Komprimierung dieser Strukturen zu einer Zunahme der internen Spannungen und endet bei einem Druck von 12.4(3)GPa für LNG und 11.7(3)GPa für LTG mit einem Phasenübergang in Strukturen mit niedrigerer Symmetrie. In dem untersuchten Druckbereich sind die Kompressibilitäten entlang der c-Achse fast identisch für LNG und LTG. Andererseits sind die Druckabhängigkeiten der a Gitterparameter dieser Materialien nur für die Ausgangsphase ähnlich, während die Achsenkompressibilitäten für die Hochdruckphasen von LNG und von LTG unterschiedlich sind. Die Volumenkompressibilitäten des trigonalen LNG und LTG sind 0.007GPa -1 , die entsprechenden Kompressionsmodule sind 145(3)GPa und 144(2)GPa. Der Kompressionsmechanismus von LNG und LTG kann wie folgt beschrieben werden: Eine Erhöhung des Drucks verursacht eine Reduzierung der Gittervolumina von LNG und LTG. Folglich verringern sich die Abstände zwischen den Ionen. Auf diese Weise werden die größten Kationen (La 3+ ) innerhalb der ab- Fläche verschoben, um die Abstände zwischen den positiv geladenen benachbarten Ionen (Ga 3+ /Nb 5+ (Ta 5+ )) zu maximieren. Auf die gleiche Weise bewegen sich die tetraedrisch koordinierten Ga 3+ -Ionen. Wegen der Anionen-Kationenbindungsverkürzung versuchen die Polyeder zu rotieren. Nun werden diese Drehungen durch die gemeinsamen Ecken und/oder Kanten der benachbarten Polyeder behindert. Außerdem werden diese Bewegungen durch die geringe Flexibilität begrenzt, die durch die Symmetrie (zwei- und drei- zählige Achsen) verursacht wird. So resultiert die Komprimierung hauptsächlich aus Verkleinerungen der Polyedervolumina. Folglich steigen unter zunehmenden Druck die Spannungen innerhalb der Polyeder, vor allem innerhalb der kleinsten Polyeder (GaO4-Tetraeder), wegen deren geringer Flexibilität. Bei einem Druck von 12(1)GPa resultiert die Komprimierung von LNG und LTG in einer Transformation aus der Hochsymmetriephase in eine Niedersymmetriephase. Es kann gefolgert werden, daß dieser Phasenübergang durch die Zunahme der Spannungen innerhalb der Polyeder verursacht wird. Die Hochdruckphase ist verzerrter als die ursprüngliche Phase und beinhaltet mehr Freiheitsgrade für weitere Komprimierungen. Die Hochdruckphasen von LNG und von LTG können in Strukturmodellen mit monokliner Symmetrie (Raumgruppe A2) verfeinert werden. Die Kompressionsmodule sind B0=93(2)GPa und B0=128(12)GPa für die Hochdruckphasen von LNG beziehungsweise von LTG. Die entsprechenden Kompressibilitäten der Hochdruckphasen sind 0.011GPa -1 für LNG und 0.008GPa -1 für LTG. Somit zeigen die Hochdruckphasen unterschiedliche Kompressibilität, die durch eine Nb 5+ - Ta 5+ Substitution gut erklärt werden kann. Die Kompressibilität der Hochdruckphase von LNG ist größer als der entsprechende Wert für das Hochdruckpolymorph von LTG. Dieses Phänomen kann durch die größere Verzerrung von NbO6- Polyedern im Vergleich zu TaO6- Polyedern gut erklärt werden, welche durch die höhere Polarisation der Sauerstoffanordnung bei Nb 5+ -Kationen verursacht wird. Außerdem sind die Kompressibilitäten der Hochdruckphasen größer als die entsprechenden Werte für die Ausgangsphasen von LNG und LTG. Die Beobachtung einer Zunahme der Kompressibilität weis auf zusätzliche Polyederverkippungen hin. In den meisten Fällen ergibt sich die zusätzliche Freiheit aus dem Symmetriebruch. Das erklärt eine (auf den ersten Blick ziemlich unerwartete) erhöhte Kompressibilität der Hochdruckphase. Zusätzlich kann sich durch ein anomales Elastizitätsverhalten eine Steigerung der Kompressibilität der Hochdruckphase ergeben. Bei einer Zunahme des Druckes über 22GPa hinaus wird die Komprimierung der monoklinen Kristallstruktur von LGN vermutlich zu einer drastischen Strukturänderung führen, die von Änderungen der Korrdinationszahlen begleitet ist. Wahrscheinlich werden ähnliche Prozesse auch im LTG statt finden, jedoch unter höherem Druck. Im folgenden Teil dieser Arbeit wird die thermische Expansion der Gitterparameter von LNG, LTG und La3SbZn3GeO14 (LSZG) dargestellt. Die Hochtemperaturmessungen wurden mit dem Pulverdiffraktometer im HASYLAB an der beamline B2 durchgeführt. Die Temperaturabhängigkeit der Gitterparameter von LNG und von LTG wurde an polykristallinem Material bei Temperaturen von Raumtemperatur bis 850°C durchgeführt. Die thermischen Expansionen der Gitterparameter von LNG und LTG sind in diesem Temperaturbereich fast identisch. Die thermischen Expansionskoeffizienten des Gittervolumens aV (24°C- 850°C) von LNG und LTG betragen 22.563(7)x10 -6 °C -1 beziehungsweise 20.651(7)x10 -6 °C -1 . Deutliche Veränderungen der Temperaturabhängigkeit der Gitterparameter werden für die a- Richtung beobachtet. Folglich ist das Verhalten dieser Materialien bei thermischer Expansion ebenso wie bei Komprimierung anisotrop. Für einen Vergleich des Einflusses von Druck und Temperatur auf die Gitterparameter von LNG beziehungsweise LTG wurden die Druck und Temperatur- Abhängigkeiten des c/a- Verhältnisses gemeinsam aufgetragen. Es zeigt sich, dass eine lineare Abhängigkeit besteht. Daraus läßt sich ableiten, dass die Änderung der Gitterparameter von LNG (LTG) während der Abkühlung von 850°C auf Raumtemperatur einer Änderung der Gitterparameter von LNG (LTG) unter Zunahme des Drucks um 1.4GPa entspricht. Die Substanz LSZG, welche in dieser Arbeit untersucht wurde, ist ein weiters Mitglied der Langasitfamilie. LSZG kristallisiert in der monoklinen Symmetrie, Raumgruppe A2. Die Temperaturabhängigkeit der Gitterparameter der monoklinen Phase von LSZG wurden mittels der Röntgenbeugung an polykristallinem LSZG bei Temperaturen von Raumtemperatur bis 800°C untersucht. Bei Temperaturen oberhalb 250(50)°C wurde ein Phasenübergang erster Ordnung festgestellt, welcher sich in Sprüngen der Temperaturabhängigkeiten der Gitterparameter des LSZG äußert. Die monokline Struktur der bei Raumtemperatur und Normaldruck stabilen Phase des LSZG entspricht der der Hochdruckphase von LNG beziehungsweise LTG. Es ist bekannt, daß die Änderungen der Kristallstrukturen bei steigenden Drucken und Temperaturen gegenläufig sind. Aus diesem Grund wird vermutet daß sich die monokline Kristallstruktur des LSZG bei Temperaturen oberhalb von 250(50)°C in eine trigonale Kristallstruktur (Raumgruppe P321) umwandelt, welche der Normaldruckphase von LNG beziehungsweise LTG entspricht. Für eine detailliertere Beschreibung des Phasenübergang von LSZG bei einer Temperaturerhöhung über 250(50)°C hinaus werden weitere Experimente benötigt. Zum Vergleich von strukturellen und physikalischen Eigenschaften seien auch die physikalischen Eigenschaften von LNG und LTG zusammenfassend dargestellt: 1. LNG- und LTG- Kristalle der enantiomorphen Kristallklasse 32 können im Gegensatz zu GaPO4 mittels Züchtung nach der Czochralski- Methode mit ausreichend hoher struktureller Perfektion hergestellt werden. 2. DTA- Messungen von LNG und LTG zeigen keine Änderungen des thermischen Verhaltens bis zu Temperaturen von 1400°C [5]. Da LNG und LTG vermutlich keine Phasenübergänge bis zu ihren jeweiligen Schmelzpunkten bei ungefähr 1470(30)°C haben, sind sie für piezomechanische Anwendungen bei hohen Temperaturen gut geignet. 3. Die Härte von LNG beziehungsweise LTG ist vergleichbar mit der von Quarz. 4. LNG und LTG sind chemisch inert und unlöslich in Säuren beziehungsweise Laugen. 5. Die Breite des Bandpassfilters von LNG oder LTG ist ungefähr dreimal größer als die von Quarz. Folglich sind LNG und LTG für Filter besser geeignet als Quarz. Im Lichte der Ergebnisse aus dieser Forschungsarbeit können folgende Empfehlungen gemacht werden: 1. Bezüglich der hoher Qualität dieser Materialien (die Halbwertsbreite der Reflexionen beträgt 0.0008°) und wegen des großen Streuvermögens, kann empfohlen werden, diese Kristalle als Test- Kristalle für die Justage an Einkristall- Diffraktometer und für Experimente mit harter Röntgenstrahlung zu benutzen. 2. Ebenso wie a-Quarz- Einkristalle [ 58 ], können diese Kristalle als interner Druckstandard in Einkristallhochdruckexperimenten benutzt werden, weil diese Kristalle eine große Anzahl von starken unabhängigen Reflexen besitzen. Andererseits kann die niedrigere Kompressibilität von LNG beziehungsweise LTG, im Vergleich zu a-Quarz, zu einer niedrigeren Druckmessungspräzision führen. Dieser Nachteil wird wiederum durch große Streuvermögen kompensiert. 3. LNG oder LTG können als Materialien für Drucksensoren bis zu sehr hohen Drucken verwendet werden. Wegen des Phasenübergangs von LNG und LTG ist der Einsatz lediglich auf 12(1)GPa begrenzt. 4. Die Temperaturabhängigkeit der Gitterparameter dieser Materialien zeigt keine Anomalie innerhalb des untersuchten Temperaturbereiches (24°C - 850°C). Somit wurde die thermische Stabilität von LNG und LTG bestätigt. Auf diese Weise können LNG und LTG im Austausch für Quarz als Substratmaterialien für Temperatursensoren sehr empfohlen werden.

Abstract: The human visual system is capable of processing visual information from fovea to the far peripheral visual field. Recent fMRI studies have shown a full and detailed retinotopic map in area prostriata, located ventro-dorsally and anterior to the calcarine sulcus along the parieto-occipital sulcus with strong preference for peripheral and wide-field stimulation. Here, we report the anatomical pattern of white-matter connections between area prostriata and the thalamus encompassing the lateral geniculate nucleus (LGN). We observe a continuous and extended bundle of white matter fibers from which two subcomponents can be extracted: one passing ventrally parallel to the optic radiations (OR) and another passing dorsally circumventing the lateral ventricle. Interestingly, the loop travelling dorsally connects the thalamus with the central visual field representation of prostriata, while the other loop travelling more ventrally connects the LGN with the more peripheral visual field representation. This is consistent with a retinotopic segregation recently demonstrated in the OR, connecting the LGN and V1 in humans. Our results demonstrate for the first time a retinotopic segregation regarding the trajectory of a fiber bundle between the thalamus and an associative visual area.
