The neural hierarchy is a powerful explanatory framework for how our brain relies on sensory information when we are active, but what if the vast majority of the movement and fitness industry only focuses on the least important sensory system? Today, I speak with my podcast producer, Tony, about the neural hierarchy. I outline what the three sensory systems in the neural hierarchy are and focus on the visual system which accounts for 70% of the sensory information that our brain receives. I discuss my own challenges with visual impairment as a young athlete, how the visual system interacts with movement and athletic performance, and why a visual deficit can potentially lead to pain and injury. I also discuss how training and activating the visual system can have surprising benefits in pain management, threat reduction, and strength and coordination.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.07.11.548562v1?rss=1 Authors: Fischer, I., Connors, T., Bouyer, J., Jin, Y. Abstract: Tau is a microtubule associated protein that plays important roles in regulating the properties of microtubules and axonal transport, as well as tauopathies associated with toxic aggregates leading to neurodegenerative diseases. It is encoded by the MAPT gene forming multiple isoforms by alternative splicing of exons 2/3 at the N-terminal and exon 10 which determines the numbers of microtubule binding repeats (3R or 4R). The high molecular weight (MW) tau isoform termed Big tau contains an additional large exon 4a generating a long projecting domain and expressed as a 110 kDa protein. Big tau was originally discovered in the peripheral nervous system but later found in selective CNS areas that project to the periphery as well as in the cerebellum and the visual system. However, there is a gap of knowledge in understanding the expression patterns and the role of Big tau during normal neuronal development and pathological conditions relative to the common low MW isoforms. Here we investigated the properties of Big tau in the retina and optic nerve and in particular its unique isoform structure as a middle MW of 90kDa and its distribution in retinal ganglion cells and axons of the optic nerve. We discovered that Big tau expresses the 4a exon as well as exon 6, lacking exons 2/3 but sharing the extensive phosphorylation characteristic of other tau isoforms. Importantly, the visual system expresses both the low and middle MW isoforms in adult retinal ganglion neurons and their corresponding axons. This is a unique structure and expression pattern of Big tau likely associated with different properties than what has been previously described, requiring more research to elucidate the detailed roles of Big tau in the visual system.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.04.22.537916v1?rss=1 Authors: Lindsey, J. W., Issa, E. B. Abstract: Object classification has been proposed as a principal objective of the primate ventral visual stream. However, optimizing for object classification alone does not constrain how other variables may be encoded in high-level visual representations. Here, we studied how the latent sources of variation in a visual scene are encoded within high-dimensional population codes in primate visual cortex and in deep neural networks (DNNs). In particular, we focused on the degree to which different sources of variation are represented in non-overlapping ("factorized") subspaces of population activity. In the monkey ventral visual hierarchy, we found that factorization of object pose and background information from object identity increased in higher-level regions. To test the importance of factorization in computational models of the brain, we then conducted a detailed large-scale analysis of factorization of individual scene parameters -- lighting, background, camera viewpoint, and object pose -- in a diverse library of DNN models of the visual system. Models which best matched neural, fMRI and behavioral data from both monkeys and humans across 12 datasets tended to be those which factorized scene parameters most strongly. In contrast, invariance to object pose and camera viewpoint in models was negatively associated with a match to neural and behavioral data. Intriguingly, we found that factorization was similar in magnitude and complementary to classification performance as an indicator of the most brainlike models suggesting a new principle. Thus, we propose that factorization of visual scene information is a widely used strategy in brains and DNN models. Copy rights belong to original authors.

Abstract: Neurons express many cell surface proteins as mutually binding key-lock molecules that can create synapses. However, the molecular mechanisms of how neurons make synapses only with preferred targets are not completely understood. Here we identified Side-IV and Beat-IIb, belonging to the Drosophila immunoglobulin superfamily, as a new key-lock combination capable of inducing synapse formation. Side-IV interaction with Beat-IIb transduces bifurcated signaling to Side-IV's co-receptor, Kirre, and a synaptic scaffold protein, Dsyd-1. Localization and genetic interaction analyses revealed that Side-IV localizes subcellularly at synapse formations defined by Beat-IIa/b and anchors Dsyd-1.Our data demonstrate that a complex made up of Side-IV, Beat-IIb, Kirre, and Dsyd-1 not only narrows neuronal binding specificity but also recruits synapse formation factors Kirre and Dsyd-1 to restrict synapse formation loci and inhibit miswiring. We propose a mechanism by which key-lock molecules set a hierarchy of preference among neuronal pairs in a complex circuit in vivo. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.02.11.528121v1?rss=1 Authors: Nisar, I. Abstract: How is curvature coded in the early human visual system? This question is the essence of basic shape recognition and may explain why humans are so successful in recognizing objects under difficult and varying environment conditions. We use the circle-polygon illusion ~cite{Khuu2002}, to reveal coding mechanisms in the early visual system. The stimulus, constructed by Sakurai's method ~cite{Sakurai2014}, is a static dark outline circle augmented with a 2 Hz pulsed luminance gradient around the inner border. Both the radius and eccentricity of the stimulus were varied in a crossed design over 1-8 deg. Observers reported a circle or the polygon order and the strength of the percept. We test a lower level account that argues for curvature opponency between neurons against a higher level account that codes for whole shapes. This higher level account supports scale invariance, a property through which we recognize objects regardless of the object's rotation (or orientation) and its size on the retina. We show the following: (1) Scale invariance, a property of the higher level visual system feature through which we recognize objects regardless of the object's rotation (or orientation) and its size on the retina, is not obeyed during adaptation. The mean order of the perceived polygon increased with stimulus size and decreased with eccentricity. It did not remain constant for a stimulus size. This demonstrates that the curvature coding occurs in the early visual system. (2) Linear regression analysis reveals that the cortical size of the stimulus is a better predictor of perceived polygon order. We computed the circumference of each stimulus in both retinal and cortical coordinates, taking cortical magnification into account. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.01.26.525790v1?rss=1 Authors: Harrison, W., Bays, P., Rideaux, R. Abstract: Perception is often modelled as a process of active inference, whereby prior expectations are combined with noisy sensory measurements to estimate the structure of the world. This mathematical framework has proven critical to understanding perception, cognition, motor control, and social interaction. While theoretical work has shown how priors can be computed from environmental statistics, their neural instantiation could be realised through multiple competing encoding schemes. Using a data-driven approach, here we extract the brain's representation of visual orientation and compare this with simulations from different sensory coding schemes. We found that the tuning of the human visual system is highly conditional on stimulus-specific variations in a way that is not predicted by previous proposals. We further show that the adopted encoding scheme effectively embeds an environmental prior for natural image statistics within the sensory measurement, providing the functional architecture necessary for optimal inference in the earliest stages of cortical processing.

Abstract: Global effects of FBA are generally limited to stimuli sharing the same or similar features, as hypothesized in the "feature-similarity gain model". Visual perception, however, often reflects categories acquired via experience; whether the global-FBA effect can be induced by the categorized features remains unclear. Here human subjects were trained to classify motion-directions into two discrete categories and performed a classical motion-based attention task. We found a category-induced global-FBA effect in both the MT+ and frontoparietal areas, where attention to a motion-direction globally spread to unattended motion-directions within the same category, but not to those in a different category. Effective connectivity analysis showed that the category-induced global-FBA effect in MT+ was derived by feedback from the IFJ. Altogether, our results reveal for the first time a category-induced global-FBA effect and identify a source for this effect in human prefrontal cortex, implying that FBA is of greater ecological significance than previously thought.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.11.11.516093v1?rss=1 Authors: Tikidji-Hamburyan, R. A., Govindaiah, G., Guido, B., Colonnese, M. T. Abstract: During development, retinal axons create broad and imprecise connections in the thalamus. This topology, very different from adults, supplies developing thalamic neurons with locally homogeneous synaptic currents and should cause spike correlation between thalamocortical neurons on a millisecond timescale. Such correlations have not been observed in vivo, at these ages, and would likely be maladaptive. Here, we use a biophysical model of the visual thalamus with the membrane and synaptic properties of 7-10 day-old mice to show that the developmentally appropriate dominance of NMDA-receptor currents and absence of strong recurrent inhibitory and excitatory connections prevents precise correlation and preserves topographic information in thalamic spikes. We illustrate possible reasons for this desynchronization using a phenomenological cortical model, which shows impaired network diversity when driven with precisely correlated inputs. Our results suggest that developing synapses and circuits evolved mechanisms to compensate for detrimental, "parasitic" correlation arising from the unrefined and immature circuit.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.08.27.505287v1?rss=1 Authors: He, L., He, Y., Lun, K., Ma, L., Du, K., Huang, T. Abstract: Retina ribbon synapses are the first synapses in the visual system. Unlike the conventional synapses in the central nervous system triggered by action potentials, ribbon synapses are uniquely driven by graded membrane potentials and are thought to transfer early sensory information faithfully. However, how ribbon synapses compress the visual signals and contribute to visual adaptation in retina circuits is less understood. To this end, we introduce a physiologically constrained module for the ribbon synapse, termed Ribbon Adaptive Block (RAB), and an extended "hierarchical Linear-Nonlinear-Synapse" (hLNS) framework for the retina circuit. Our models can elegantly reproduce a wide range of experimental recordings on synaptic and circuit-level adaptive behaviors across different cell types and species. In particular, it shows strong robustness to unseen stimulus protocols. Intriguingly, when using the hLNS framework to fit intra-cellular recordings from the retina circuit under stimuli similar to natural conditions, we revealed rich and diverse adaptive time constants of ribbon synapses. Furthermore, we predicted a frequency-sensitive gain-control strategy for the synapse between the photoreceptor and the CX bipolar cell, which differ from the classic contrast-based strategy in retina circuits. Overall, our framework provides a powerful analytical tool for exploring synaptic adaptation mechanisms in early sensory coding. Copy rights belong to original authors.

Huberman Lab Podcast Notes Key Takeaways How you visualize a goal or problem in your mind dictates how well you lean into that goal: whether you will be able to meet the goal, how you feel after, and your capacity to tackle larger goals“Proximity to a goal increases the investment and resources that people use to meet that goal.” – Dr. Emily BalcetisSet goals that are challenging but not impossible – and – not so easy that it's a no-brainer or requires minimal effortOverweight/deconditioned people see the world as more challenging: hills are steeper, finish lines are further – which shifts these people into a state of fatigue and makes it harder to start & overcomeTrouble finishing your run? Focus on intermediate targets along the way which makes the goal feel closer and you push harderVisualization/vision boards alone are not enough! To put visualizations into action: (1) set a plan – break it down into practical day-to-day; (2) think about obstacles that stand in the way of success so they don't surprise you along the wayWhen setting goals you can't tangibly see, don't count on your memory – write down progress along the way or use an app to help you more accurately track & reflect on progressRead the full notes @ podcastnotes.orgMy guest this episode is Dr. Emily Balcetis, PhD, Professor of Psychology at New York University (NYU). Dr. Balcetis' research focuses on how our perception of the world, particularly our visual perceptions, influences our level and persistence of motivation, how we conceptualize goals, actual goal achievement, and our emotional state as we pursue goals. Dr. Balcetis explains how to best visualize and overcome challenges in pursuit of larger, complex goals. We also discuss the science of how to define goals and intermediate milestones, overcome obstacles, and effectively track progress. This episode highlights science-based, immediately actionable tools that anyone can use to set and achieve physical and/or cognitive goals more effectively.

Dr. Balcetis explains how to best visualize and overcome challenges in pursuit of larger, complex goals. We also discuss the science of how to define goals and intermediate milestones, overcome obstacles, and effectively track progress. This episode highlights science-based, immediately actionable tools that anyone can use to set and achieve physical and/or cognitive goals more effectively.

Prof Michael Barnett, Director Sydney Neuroimaging Analysis Centre and Professor of Neurology, University of Sydney, joins JNNP's Podcast Editor, Colin Mahoney, to discuss how the use of Alemtuzumab may have longer-term impacts on improving one of the most commonly involved neurological pathways, the visual system, in multiple sclerosis (MS). Prof Barnett discusses his team's results after following up patients with highly active MS for 24 months, using multifocal visual evoked potentials and advanced neuroimaging. He also talks about what this means for future remyelination strategies. Related paper: https://jnnp.bmj.com/content/92/12/1319

Where do light sensitivities, or photophobias come from? You have photophobia if you are more sensitive to light coming in, and have an increase in migraine symptoms with light. Research shows 80% of migraine sufferers have this, it's a very common problem. We will discuss colors, colorblindness, and blue light blocking eye glasses.

In this two part series we talk about how there are different aspects of the visual system that can play into headaches and migraines. This episode focuses on eye strain - we will talk about the common problem of convergence insufficiency. This is a common, overlooked problem that can play a role in headaches. We will talk about all aspects of it: What is it? Who gets it? How do they get it? What nerves and muscles are impaired to cause this problem? How does it relate to headaches? How in our clinic do we assess and treat this? By the end of this episode you will fully understand convergence insufficiency and you will know what to do about it.

Abstract: Sensory processing relies on the correct development of circuits connecting thalamus and cortex. Visual corticothalamic axons (CTAs) invade the thalamic dorsolateral geniculate nucleus (dLGN) of the thalamus following an early postnatal time-regulated programme in mice. Retinal spontaneous activity influences the thalamic incursion of CTAs, however, the perinatal thalamus also generates intrinsic patterns of spontaneous activity whose role in modulating afferent connectivity remains unknown. Here, we found that patterned spontaneous activity in the dLGN is critical for the proper spatial and temporal innervation of CTAs. When the spontaneous dLGN activity is disrupted in vivo, CTA innervation is severely delayed until eye-opening. Indeed, visual input influenced the temporal development of CTAs by modulating thalamic activity, as embryonic enucleation enhanced thalamic calcium waves and accelerated the entrance of CTAs into the dLGN. Our results show that patterned spontaneous activity in the perinatal thalamus is a key element driving the wiring of visual circuits. Copy rights belong to original authors.

To comprehend how the brain performs efficient computation, it is important to understand the way sensory information is represented in the nervous system. Under natural conditions, sensory signals have to be processed with sufficient accuracy under functional and resources constraints. Here I use motion vision in the fly Calliphora vicina to study the influence of two behaviorally relevant environmental properties - temperature and light intensity - on the representation of motion information in the responses of the neuron H1. The goal was to quantify how these environmental properties affect the response variability, information content, coding efficiency and temporal scale. I show that the firing precision is determined largely by the light intensity rather than by temperature. Moreover, a better firing precision barely improves the information rate, which closely follows the mean firing rate. Altogether, my results suggest that the robustness of the motion information processing against temperature variations depends on the quality of the input signal. Furthermore, flies seem to use the input signal-to-noise ratio to improve the information rate and reduce the time-scale of the response simultaneously, by increasing the mean firing rate, rather than the firing precision.

Have you ever seen a web site so clear, logical, and exquisitely composed it made you stop in your tracks? Have you wondered how the designer achieved such a stunning and cohesive design? In this presentation, Kimberly Elam, designer and author of the best-selling "Geometry of Design" and "Typographic Systems" will reveal the mysterious relationships between proportion, visual systems, composition and aesthetics. Too often excellent conceptual ideas suffer during the process of realization, in large part because the designer did not understand the essential visual principles. This presentation explores these elements and how they work by examining how the use of visual principles informs, even creates, beauty in typographic design, but, more importantly, how you can use these techniques to create cohesiveness in your own design. The wide range of visual examples are both informative and insightful, and any designer can benefit from learning or revisiting the rules governing the basics of typographic design. Kimberly Elam is a writer, educator, and graphic designer. She is currently the Chair of the Graphic & Interactive Communication Department at the Ringling College of Art + Design, Sarasota, Florida, where she has developed an academic minor in the Business of Art and Design. Her first book, Expressive Typography - Word as Image, identifies and analyzes methods by which words can transcend didactic meaning and become images. Geometry of Design - Studies in Proportion and Composition, visually illustrates the connection between classic proportioning systems and modern graphic design, industrial design, illustration, and architecture. Grid Systems - Principles of Organizing Type puts forth a clear methodology for understanding and learning the grid system of composition. Her most recent book, Typographic Systems - Rules for Organizing Type presents an innovative series of nontraditional, rule-based, visual language systems for typographic composition. Her current work focuses on the development of a series of innovative ebooks and print-on-demand books for design education on her website, StudioResourceInc.com.

Introduction: Mild Cognitive Impairment (MCI) is a cognitive stage between normal aging and Dementia. It is a heterogeneous group of patients, where most of them develop Alzheimer’s disease (AD), others stabilize, and a few revert to normal. AD’s first clinical symptoms are related to memory, but it has been shown that AD involves also a processing disorder in the visual sensory pathways. Accurate visual function facilitates memory, attention and executive functions, so that perceptual dysfunction contributes to the severity of cognitive impairment. Objective: The objective of the work is to measure changes in activation in the visual system between MCI patients and old Healthy Control (HC) subjects, using two different visual processing tasks with functional Magnet Resonance Imaging (fMRI). This is the first study which makes such a comparison between MCI and HC using fMRI. Methods: Brain activation was measured using fMRI. The MCI group was composed of 16 subjects and the HC group was composed of 19 subjects. All subjects performed two tasks: location matching (position of objects) and face matching (characteristics of the objects), which selectively activate one of the visual system pathways in healthy people. Answers were given by pressing a single button. Results: Performance of the task was not significantly different in both groups. The HC group selectively activated ventral pathway for face matching and the dorsal pathways for location matching. In contrast the MCI subjects did not selectively activate the ventral and dorsal pathways of the visual system. Additionally they showed higher activation in the left frontal lobe compared to HC when performing the location matching Task Conclusions: The results suggest that even when behavioural performance between groups is the same, the neural system which supports performance may differ. MCI subjects compensate their deficits using additional brain areas to help them to maintain performance. In this case MCI subjects used the left frontal lobe in addition to perform the location matching task. This work presents the usability of brain imaging techniques especially fMRI to better understand the underlying pathology of MCI and its subtypes as prodromal conditions of AD.

Neuronal activity, both intrinsically generated and sensory-evoked, is known to play an important role in the development of the brain. Sensory experiences continue to exert a strong influence on the functional connectivity of neuronal circuits, especially in the cerebral cortex, allowing for learning and adaptation to an ever changing environment. The visual system provides a convenient and well established model to study both development and experience-dependent plasticity of neuronal circuits. The aim of this thesis is to employ the mouse visual system to explore how neuronal activity influences the formation of brain circuits and mediates their experience-dependent modification later in life. In the first part of this thesis (Chapter 2), I examined the role of retinal activity in the formation of topographic maps in a target region of retinal ganglion cells. It is generally assumed that in order to obtain such highly precise and ordered maps during development, spontaneous patterns of neuronal activity are crucial for the refinement of connections. Applying intrinsic signal imaging to mouse superior colliculus (SC), I confirmed this assumption by showing that functional connectivity is less precise in transgenic mice with disrupted patterns of retinal ganglion cell activity. In comparison to normal mice, visual stimuli activated larger, less defined regions in the SC in mice lacking early retinal waves. Surprisingly, I also found that the overall topographic organization was affected by the lack of correlated spiking in the retina. Although the rough retinotopic organization was maintained, the map showed substantial distortion, indicating that patterned retinal activity before eye-opening plays a more important role in topographic map formation than previously thought. Later in development, sensory-evoked activity is equally influential in shaping functional connectivity, since altered sensory input induces strong changes in cortical circuitry. Closure of one eye for a few days (monocular deprivation, MD), for instance, substantially changes cortical responsiveness to the two eyes, shifting ocular dominance (OD) towards the non-deprived eye. This paradigm therefore provides a powerful model system for experience-dependent plasticity. In Chapter 3, I used intrinsic signal imaging to assess the magnitude of cortical responses evoked by stimulation of the two eyes in order to explore OD plasticity in mouse visual cortex. I confirmed recent, debated findings in demonstrating strong MD-induced plasticity in adult animals, which was mediated by partly different mechanisms than in juvenile mice. I also found that restoring binocular vision after MD led to full recovery of eye-specific responses at all ages. Interestingly, the prior experience of altered sensory input seemed to be somehow preserved in cortical circuits, such that subsequent cortical adaptation to the same experience was improved. A second MD resulted in much faster and more persistent OD shifts. This enhancement of plasticity was highly specific, as it was only observed for repeated deprivation of the same eye, indicating that a lasting trace was established in cortical connections by the initial experience. In Chapter 4, I explored OD plasticity in greater detail by monitoring network activity at the level of individual neurons with in vivo two-photon imaging of calcium signals. Monitoring calcium transients associated with neuronal activity in up to hundred cells simultaneously, enabled me to examine MD-induced changes in the functional properties of each neuron independently. I found that, in general, deprived eye responses were weakened and non-deprived eye responses strengthened after MD in juvenile mice, as was expected from previous population response measurements. Neurons still dominated by deprived-eye inputs, however, did not lose their responsiveness, but rather exhibited enhanced responses following MD. This strongly suggests that homeostatic plasticity acted on these cells during deprivation and caused an up-scaling of their responsiveness, while neurons also receiving substantial input from the non-deprived eye shifted their responsiveness towards that eye. Both competitive and homeostatic processes therefore seem to operate during OD plasticity, depending on the distribution of functional inputs in individual cells. In conclusion, the work presented in this thesis provides further insight into the role of activity-dependent mechanisms in determining and shaping functional connectivity in the brain.
