Hello Interactors,All the talk and evidence of AI, chips in the brain, and robotic overlords has created emotions ranging from hysteria to malaise to clinical depression. How much of this is caused or influenced by narratives spun by favored voices telling tall tales of proximal parables and are there other ways to think about our brain than just a processor? Let's find out…THE MENTAL MYTHS OF SILICON AND SYNAPSESOur brain is an energy intense organ. It consumes 20% of our energy but accounts for just 2% of our body weight. To manage this high demand for energy, the brain employs various strategies to simplify tasks and processes. One of those is to simplify how the world works. Like dividing it into discernable individual component parts.In a world increasingly seduced by these crisp edges of in groups and out groups, there exists a tribe of techno-optimists, guardians of an old tale, who look to the brain as humanity's ultimate processor and a promise and desire for digital immortality. This romanticized notion of the “mind as computer” is facing competition as feats of AI reveal a seemingly superior capability to their own self-assuming super-intelligence. So, they want their outdated hardware upgraded. It's all positioned as cutting edge and futuristic but harks back to the clockwork dualistic and mechanistic universe of the Enlightenment.We've been preached a digital gospel that suggests the warm wetware within our skulls operates like baked silicon chips, crunching data of daily existence with the cold precision of a CPU. Yet, simmering in the biochemistry that hosts these digital dreams are ripples of evidence captured and crunched by computers and displayed in the form of MRI's, fMRI's, PET scans, SPECT scans, NIRS, and MEG's. These images lead some cognitive scientists, with the help of various forms of AI, to slowly dismantle the mechanistic metaphor of ‘the brain as CPU', piece by intricate piece.The metaphor of the brain functioning as a processor is as old as Alan Turing and the mid-20th century computational theories that birthed computer science. These ideas and experiments propagated as mass media proliferated and now serve as common conceptions of how the mind works. Other historical and cultural factors contribute to the persistence of this metaphor and perpetuated among teachers, scientists, and attention seeking tech moguls.But it was centuries before, during the Enlightenment and the scientific revolution, that a significant shift towards rationalist, determinist, and mechanistic views of nature were put forth by figures like René Descartes and Isaac Newton. The world and its phenomena, including human beings and human thought, began to be understood in terms of mechanical laws and principles, laying the groundwork for comparing the brain to a machine.The advancements in machinery and technology during the Industrial Revolution further reinforced the mechanistic view of life processes, including human cognition, making it easier to draw parallels between the operations of machines and the functions of the human brain. I recently wrote about Mary Shelley's Frankenstein as a prime example from that period.Fast forwarding a century later, to the 1970s, I remember watching the “Six Million Dollar Man” on TV as a kid. This show was based on a Martin Caidin novel called Cyborg depicting an astronaut who survives a plane crash and is brought to life by replacing body parts with robotics. The “Six Million Dollar Man” was soon joined by “The Bionic Woman” and episodes that featured the faces of human robots being ripped off to reveal a computer inside. Naturally, these two computer-powered bionic superpowers worked as secret agents in U.S. Office of…wait for it…“Scientific Intelligence.”Source: YouTubeThis was all occurring alongside emerging discoveries in artificial intelligence and cognitive science, further cementing the brain-CPU analogy. Like science fiction writers and directors, early AI researchers and scientists aimed to replicate human cognitive processes in computers, leading to conceptual overlaps between how brains and computers function in science and society.The CPU metaphor provides a simplified way to understand the complex workings of the brain, making it accessible to people without specialized knowledge in neuroscience or cognitive science. This metaphor continues to be used in educational contexts to teach basic concepts about brain functions, reinforcing its prevalence.The tendency toward reductionism — to reduce complex phenomena to their simplest components — is present in many scientific and engineering disciplines and has long contributed to the organ-as-part metaphor. Viewing the brain as akin to a computer's CPU aligns with reductionist approaches reminiscent of those early Enlightenment thinkers seeking to understand biological systems by dissecting their individual parts and drawing useful, but also isolated and simplified conclusions.While the brain-CPU metaphor has historical roots and provides a convenient framework for understanding some aspects of cognitive function, many believe it is ultimately flawed. It can overlook the brain's integrated and dynamic nature, its entanglement within a larger biological organism, and its continuous interaction with a complex environment. These are themes under exposed and under explained in popular science, media, and most of the tech industry.The growing recognition of these limitations, particularly within fields like 4E cognitive science (embodied, embedded, enactive, and extended cognition), is leading to the development of more nuanced and holistic models of cognition that transcend simplistic mechanical analogies.Do we have the energy to spare our brain so we may better understand it?EMBODIED MINDS EMBEDDED, EXTENDED, AND ENACTIVE The 4E framework in cognitive science highlights the brain's integrated and dynamic nature. Advances in neuroscience have shown that the brain is not a static organ with fixed functions but is highly malleable, capable of reorganizing itself in response to learning and experience. This plasticity allows for adaptability and resilience necessary for its survival, characteristics not accounted for in the rigid structure of a CPU.The brain's structure is composed of complex, interconnected networks that support a wide range of functions, from basic sensory processing to higher-order cognitive tasks. These networks do not operate in isolation but are dynamically interacting and reconfiguring based on internal and external demands.The brain's function is also modulated by a variety of neurotransmitters that influence mood, cognition, and behavior. This biochemical layer adds a level of complexity to brain function that is absent in computer CPUs today. This means the brain is intimately connected to the biology of the body, receiving continuous sensory inputs and sending commands to our organs and limbs. This sensory-motor coupling is foundational to cognition, emphasizing the role of bodily interactions with the world and how our brain processes it.Research supports this concept. Cognition is something that is embodied in us, where cognitive processes are grounded in sensory and motor systems. For example, studies on mirror neurons suggest that understanding others' actions involves simulating these actions in our own sensory-motor systems.For instance, when a child observes an adult using a tool, such as a hammer, the mirror neurons associated with the motion of hammering may fire in the child's brain, despite the child not physically performing the action. This neural activity can help the child understand the action and later replicate it, contributing to the learning process.Another example is in the understanding of emotions. When we see someone smiling or frowning, our mirror neuron system may activate the same facial muscles involved in smiling or frowning, contributing to an empathetic response. This internal mimicry can help us to 'feel' what the other person is feeling and develop a better understanding of their emotional state.The brain is in continuous interaction with the complex environment in which we exist. It is embedded in an environment that it continuously interacts with, influencing and being influenced by it. This interaction is not merely passive; the brain actively constructs perceptions and meanings based on environmental inputs.This enactive perspective posits cognition arises through a dynamic interplay between an organism and its environment. Cognitive processes such as perception and action are therefore inseparable and co-determined. In the example of a child learning to use a hammer, they learn to grasp the handle not just by observing but through a process of trial and error. This involves actively engaging with the object and learning from the outcomes of these interactions thus enacting cognition through interactive processes.These dynamic interactions are extended beyond the brain and body to include tools, like a hammer, but also computers, mobile phones, and automobiles. These tools become part of the mind's cognitive architecture. This perspective challenges traditional notions of cognition as being confined within the boundaries of the individual, proposing instead that objects and devices in our environment can function as extensions of our cognitive system when they are deeply integrated into our mental activities.As the brains of neuroscientists interact with each other, their embedded and embodied brains are synthesizing an ever-evolving understanding of cognition that is more integral than dichotomous, more holistic than dualistic. Even as the brain employs cost-cutting simplification strategies, a rich emergent complexity emerges that further defines our cognitive reality.The old metaphor of the brain as a CPU, once a middle 20th-century marvel, is gradually yielding to a perspective that sees the brain not as a solitary processor but as part of a dynamic, integrated system of organism and environment. As techno-optimists laud AI and digital immortality, praying to dualistic gods, the minds of some neuroscientists are extended by imaging tools powered by CPUs, presenting a model of cognition far from the mechanistic. Instead, they argue our brains are enmeshed in a dynamic and fluid biological existence.It is here, in the flowing network of neurons and scientific narratives, that the future of understanding the human mind is taking shape. Even as I write this and you read it, we are moving our brain from the rigidly digital dualistic understanding to the fluidly enactive. In doing so, our brains are redefining our place within this emergent organism-environment system we call life using as little energy as necessary.References:Knyazev, G. G. (2023).

In this episode, Dr. Robert Jacobs and I discuss the concept of thresholds in exercise physiology and the ongoing debate surrounding their existence. We explore the importance of understanding and measuring first threshold, which marks the shift from maximal fat oxidation towards carbohydrate oxidation during exercise. We discuss the challenges of accurately measuring thresholds and the need for trend analysis over time. We also highlight the significance of Fatmax, the point at which the body maximizes fat oxidation, and its potential applications in performance and health. This conversation explores the concept of Fatmax and its relationship to performance and fitness. We discuss the differences between Fatmax and other thresholds, such as ventilatory/gas exchange and lactate threshold. We also examine the impact of nutrition and training interventions on Fatmax. The conversation highlights the importance of low-intensity exercise and the confusion surrounding training zones. Various methods to measure lactate threshold and estimate the first threshold are discussed. As always we emphasize the principles of consistency, specificity, and progression in training. The benefits of Zone 2 training and the influence of exercise modality on intensity are also explored. TAKEAWAYS 1) Thresholds in exercise physiology are points that mark shifts in metabolic processes and physiology during exercise. 2) The existence of thresholds has been a topic of debate, but they are valuable in identifying metabolic transitions and informing training. 3) Accurately measuring thresholds can be challenging, and trend analysis over time is crucial for understanding individual responses. 4) Fatmax occurs at a different percentage of VO2 max for each individual, and it can be influenced by nutrition and training interventions. 5) Low-intensity exercise is often neglected but plays a crucial role in improving efficiency and fat oxidation. 6) Different methods, such as lactate measurement and NIRS, can be used to estimate the first threshold.

BARI (ITALPRESS) - Sono stati presentati questo pomeriggio a Bari, nel padiglione della Regione Puglia della Fiera del Levante, i risultati dell'attività ispettiva del Nirs, il Nucleo ispettivo regionale sanitario coordinato dall'avvocato Antonio La Scala. Oltre a quest'ultimo, erano presenti la dirigente ad interim del Servizio Ispettivo Angela Guerra, la professoressa Angela Pezzolla (componente Nirs) e il governatore Michele Emiliano, che ha approfittato dell'occasione per ringraziare personalmente gli ispettori per la dedizione e la professionalità profusa, consegnando loro una pergamena.Sono stati tanti i dati emersi. Su tutti, quelli relativi alle 45 segnalazioni verificate e per le quali è stato emesso verbale ispettivo da parte degli ispettori incaricati. Di queste, quattro si sono concluse con la richiesta di follow-up e di azioni di miglioramento, 14 con la richiesta del solo follow-up da parte del Servizio Ispettivo, otto con indicazioni di azione di miglioramento da suggerire alle Direzioni di riferimento e 19 senza richiesta di follow-up né di azioni di miglioramento poiché la segnalazione non è sembrata fondata o le azioni correttive intraprese ai vari livelli sono state ritenute adeguate, oppure ancora se si è trattato di episodi giudicati isolati.“Oggi - ha affermato Emiliano - abbiamo presentato l'attività del Nirs, che è un nucleo ispettivo voluto dalla presidenza della Regione Puglia e che rappresenta il più poderoso sistema di controllo di tutte le attività della sanità pugliese, pubblica e privata. Questo lavoro ha dato vita a numerosissime ispezioni, approfondimenti, dei quali oggi abbiamo dato conto. Esiste quindi un sistema (a prescindere da quello ordinario gestito dalle Asl, fondato ovviamente sul potere disciplinare di ciascuna direzione strategica) basato su un controllo politico di ogni questione che riguarda la sanità. Ogni cittadino, persino in forma anonima, può segnalare situazioni che hanno bisogno di essere approfondite. Nel Nirs lavorano come volontari (perché nessuno è pagato, se non i dipendenti del sistema sanitario stesso in servizio) numerosi ufficiali di polizia giudiziaria di grande esperienza che si sono occupati delle indagini forse più importanti che sono state fatte negli ultimi anni in Puglia. E, ripeto, prestano la loro attività gratuitamente. Quindi oggi c'è stata anche la consegna di un riconoscimento a tutte queste persone che stanno lavorando per il popolo pugliese”.“La Puglia - ha aggiunto La Scala - è l'unica regione ad avere un organismo come il Nirs. È la dimostrazione di come un'amministrazione seria non metta la polvere sotto il tappeto. Di questo bisogna rendere merito al presidente Emiliano. La nostra attività si è concentrata su due grandi filoni. Il primo è quello della malasanità, intesa come la denuncia di interventi errati e cure sbagliate. È emersa una criticità sulla quale bisogna lavorare, ovvero il potenziamento del rapporto comunicativo-informativo tra paziente e struttura. Da questo punto di vista sicuramente bisognerebbe rafforzare e trovare strumenti che possono facilitare la comunicazione con il paziente. Sotto il profilo della cosiddetta mala gestione ci sono tante problematiche nelle Rsa. Serve rendere meno burocratice le procedure di accesso e di accreditamento, per consentire di lavorare in maniera più serena. Anche nell'ambito delle società in house occorrono miglioramenti. E poi ci siamo occupati del problema dei cosiddetti furbetti dei vaccini. Come responsabile del Nirs mi permetto di proporre l'intensificazione dei controlli, perché sono fondamentali. In questo modo, dal paziente al personale della struttura sanitaria, ognuno si sentirà più responsabile rispetto all'attività che svolge”. xa2/vbo/gtr
Jem Arnold is a PhD candidate at the University of British Columbia, where his primary research focuses on sport-related vascular conditions. Jem is a physiotherapist, a physiologist, and an avid cyclist and trail runner interested in optimising endurance training. IN THIS EPISODE YOU'LL LEARN ABOUT: -Including training above "threshold" in your program improves VO2max, but may not improve Time Trial performance more than training only up to threshold-intensity (a recent meta-analysis) -Implications of these findings for athletes and coaches - what does it mean in practice? -How can we interpret group-level research for individual-level training programming and application? -Why even big sample sizes and data sets might be of limited value for the individual - the larger the sample size, the greater the confidence in the "group mean", but individual prediction may still be way off -What is the variability of heart rate, RPE, lactate, and muscle oxygen saturation from day to day?

Seguramente no has leído el “Manual de Economía Política” de Vilfredo Pareto; yo tampoco lo he hecho. Pero, es seguro también, que has oído hablar del “principio de Pareto”, por el cual, el 80% de los resultados dependen del 20% de los factores, por lo que conviene destinar nuestro tiempo y esfuerzo a estos últimos, si queremos ser eficientes y eficaces; si queremos que cada minuto de trabajo invertido cuente en el resultado final. Y, por lógica, destinar tiempo y esfuerzo al 20% de cosas que de verdad importan, implica olvidarse de toda esa miríada de cosas muy molonas, sí, pero que, en el mejor de los casos, podrían darte un 1% o un cero-coma-algo por ciento de rendimiento. Si te interesa saberlo, Vilfredo Pareto fue un economista italiano que, al analizar el reparto de tierras en su país, se percató de que el 80% de ellas pertenecía a un pequeño grupo de terratenientes, que representaban solamente el 20% de la población. El caso es que ese principio 80/20, que el 20% de los factores nos proporcionan el 80% del resultado y que el 80% restante de factores, todos juntos, con suerte podrían darnos un 20% extra de rendimiento, también aplica al trail-running, que es lo que aquí interesa. Ocurre así que, de todos esos sistemas de entrenamiento, productos de nutrición y recuperación y gadgets de monitorización que existen, esas estancias en altura o tiendas de hipoxia, esos lactatos, HRVs, NIRS o monitores de glucosa, esos nitratos, bicarbonatos o cetonas o esos electro-estimuladores, botas de compresión o crioterapias, ninguno merece de veras la pena, salvo que seas profesional o, si acaso, amateur mega-comprometido, y quieras explotar todas las ganancias marginales posibles para ganar un 1 o 2% de rendimiento. Las cuatro cosas que te van a dar, como mínimo, el 80% de resultado son poco glamurosas, son cosas que no querrías publicar en Stories de Instagram o en TikTok, son bastante old-school, pero, insisto: funcionan. No descubro la pólvora si te digo que esas cuatro cosas son (1) acumular mucho trabajo, mayoritariamente de baja intensidad, pero incluyendo también algunos workouts de alta intensidad, (2) observar tus sensaciones antes, durante y después del entrenamiento, (3) nutrirse adecuadamente antes, durante y después del entrenamiento, pudiendo suplementar con productos probados, como cafeína, creatina o proteína, y (4) descansar. Bien, ya tenemos las cartas sobre la mesa. Por un lado, tenemos las cuatro cosas que sabemos que funcionan: acumular trabajo (casi todo a baja intensidad y algo, a alta), monitorizar la carga del entrenamiento observando las sensaciones, nutrirse en función del gasto calórico y la destrucción muscular, descansar tanto y tan bien como se entrena. Y, por otro lado, tenemos una retahíla de cosas súper “Fancy”, que además están súper de moda y las vemos en las Stories de Instagram o son materia de revisiones sistemáticas de estudios, pero con mínima efectividad, para la masa trail runner popular: sesiones dobles a umbral, entrenamiento en ayunas, entrenamiento en altura, tiendas de hipoxia, sauna, psicólogo deportivo; medidor de lactato, estimador de potencia, termómetros de core, HRV, NIRS, análisis de sangre trimestrales, monitores de glucosa; geles high-carb, pastillas de sales, nitratos, bicarbonato de sodio, cetonas, MCTs; botas de compresión, electro-estimuladores, crioterapia, multi-vitamínicos. Una vez más, hoy toca bajar de la nube a la realidad y recordar lo que ya sabemos: que el trabajo duro, la nutrición, el descanso y un poco de sentido común son lo que va a llevarnos a nuestra mejor versión y que, el resto de sistemas, productos y gadgets, no pueden sustituir lo anterior. Los atajos no existen, nos guste o no. Ahora, que me he ganado ya unos cuantos enemigos, sin más dilación, vamos al turrón. --- Sígueme en https://www.instagram.com/correrporsenderos/ donde publico píldoras sobre trail running a diario en Stories .

The Wandering Journo has just returned from one of the most exciting secondments of my now three-decade journalism career - from the Cathedral of Sport the great MCG, where I was part of the National Indigenous Radio Service team covering the 2023 AFL grand final. And I have brought back a glimpse of the action for Streets of Your Town from behind the scenes of the National Indigenous Service broadcast box, where the incredible NIRS commentators call the grand final live. From this tiny booth they broadcast the finals action to some of the most remote communities in outback Australia. Indigenous players are the backbone of this great Australian game, and I speak to two NIRS broadcasting legends - Ron Rogers, and former Collingwood player Chris Egan. They both give their insights into the magic that Aboriginal players bring to Australian Rules Football, and the privilege they feel broadcasting ball-by-ball to hopefully plant the seeds of dreams for more Indigenous players from remote communities to become part of the great game. NIRS AFL commentator legend Ron Rogers has 25 years calling grand finals under his belt, and as he reveals not only does he do the commentary, he sets up the microphones and equipment before each game to broadcast on the AFL website, and to NIRS affiliated radio stations around the country. While Chris Egan brings his experience as a former footballer for Collingwood to the broadcast team, giving insights into how players prepare and cope with the the big pressure games.

Can you imagine the world of neonatal medicine from the lens of cutting-edge research and innovative practices? This week, we unpack the complexities of neonatal care, shining a light on the vital role of antibiotic prophylaxis in preventing secondary kidney damage for infants with severe VUR. We review a landmark study published in the New England Journal of Medicine, focusing on the use of continuous antibiotic prophylaxis for infants with severe vesicoureteral reflux. Not stopping there, we dissect the methodology, delve into the results, and ponder on the implications of this ground-breaking research.We also enter the intriguing realm of neonatal sepsis and enteral feeding in very low birth weight infants. Using guidelines from pediatricians and nephrologists, we scrutinize perinatal risk factors and the captivating findings of a meta-analysis published in the Journal of Maternal, Fetal and Neonatal Medicine. We explore the discrepancy between ordered vs administered enteral feeds, and the crucial need to include the entire NICU team to achieve better outcomes.In the final chapters, we tackle the tough topic of neurodevelopmental outcomes following preterm birth and the associated challenges in prognosis delivery. You'll hear from recent paper discussing insightful views on delivering prognoses and balancing clinical and epidemiologic reasoning with clear communication. Join us as we weave through the intricate tapestry of neonatal care, illuminating the long-term consequences of extreme premature birth and exploring the perspectives of those with firsthand experience of prematurity.

Moxy Monitor is a wearable NIRS device (muscle oxygen monitor) that measures the balance of oxygen delivery and oxygen utilization in the muscle non-invasively. Interest is growing about the potential to use this technology in sports like CrossFit in order to better monitor intensity, individualize training and educate athletes. In this conversation, I talk with Sebastian, Damien and Assaf about the potential utility of Moxy Monitor for CrossFit training and coaching. I begin with a QUICK refresher on Moxy theory and practice. If you want something less rushed, watch this :https://www.youtube.com/watch?v=L9glY_uokKU. We then delve into how to test conditioning with Moxy, how to interpret the results, how to train with Moxy Monitor in a CrossFit context (for both specific and general testing) as well as respiratory training and coaching philosophy. This was a very fun exchange! I hope to have more of this kind in the future. If you agree, please leave a comment below to support the channel!

Ecological News includes Biden's White House turning to geoengineering and Ohio's dark money groups that are controlling the State legislature. NOTE: No episode next week.
On this episode, your host Joe Dalton welcomes Joseph McMahon to talk about RialtoLabs, a company focused on utilizing underutilized technology. Near-infrared spectroscopy (NIRS) has been around for a while, but the recent convergence of technologies such as cloud, and AI machine learning algorithms aligning with the increased quality and availability of handheld portable NIRS devices have opened up new possibilities for its field applications.McMahon also discusses how NIRS can be integrated into a laboratory's workflow, which can reduce the use of toxic chemicals and consumables by 75%. Additionally, NIRS makes it easier to analyze soil health, which is critical in delivering ecosystem services. They discuss how the use of this technology can decrease a laboratory's overhead costs while also increasing its productivity and profitability. The conversation then turns to RialtoLabs, McMahon talks about how the company was formed and how they are working to create an AI model that can provide accurate nutrient information analysis in real-time. They also discuss the potential for near-infrared spectroscopy in developing nations and other regions. www.joedalton.ie Hosted on Acast. See acast.com/privacy for more information.

In this discussion, we cover her work on characterizing the variability of coherence as it relates to aging and how this coherence is increased by providing subject with ketones - an alternate source of energy to glucose. We then go into her work in modeling brain circuits and determining where the circuitry is altered across trajectories of disorders. In this context, we briefly discuss her work characterizing the effects on amygdala activation by different composition of inhaled perspiration - either that produced in a fear state vs that produced through exercise. Lastly, we discuss her lab's work on neuroblox - a simulation program for testing circuit models of the brain and how it may open up the diagnostic value of brain imaging data. Guest: Lily Mujica-Parodi, Ph.D. is Director of the Laboratory for Computational Neurodiagnostics (LCNeuro) at Stony Brook University. LCNeuro's research focuses on the application of control systems engineering and dynamical systems to human neuroimaging time series (fMRI, MEG, EEG, NIRS, ECOG), with neurodiagnostic applications to neurological and psychiatric disorders. One of LCNeuro's primary goals is to identify key points of failure in the regulation of neural control circuits which, depending upon how they break, lead to signs and symptoms that cluster as distinct psychiatric diagnoses. As a test case for this approach, her lab is working to understand how the prefrontal-limbic circuit “computes” potential threat in the face of incomplete sensory data, across a clinical spectrum that ranges from pathological fear (generalized anxiety disorder, phobia, post-traumatic stress disorder, paranoid schizophrenia) to recklessness. A second direction at LCNeuro considers fMRI connectivity as the solution to an optimization problem imposed, in part, by metabolic constraints at the mitochondrial scale. Her group uses biomimetic modeling to predict trajectories, based on biological “rules” of energy optimization, which are then validated against data. Experimentally, they expand and contract neurons' access to energy while observing consequent self-organization and re-organization of networks. The hope is that this work will have important implications for understanding brain aging; specifically, the epidemiologically observed impact of insulin resistance on cognitive decline.
Zapraszamy na drugi już odcinek rozmów o rozwoju mózgu małych dzieci. W studiu Wszechnicy spotkali się prof. dr hab. Ewa Haman i dr hab. Przemysław Tomalski, grudzień 2022 r. W przestrzeni publicznej temat mózgu pojawia się bardzo często, krąży dużo pseudonaukowych treści, często nie sprawdzonych i wątpliwej jakości. Profesor Przemysław Tomalski na rozwoju mózgu się zna. Jako ekspert opowiada nam więc o rozwoju mózgu małych dzieci i o tym co rodzice powinni na ten temat wiedzieć. Rozwój mózgu nie przebiega jednostajnie, monotonnie czy równomiernie na przestrzeni pierwszych lat. Pierwsze 3 lata życia dziecka są kluczowe. Badania mózgu pokazują, że w tym okresie (a zwłaszcza na przestrzeni pierwszego roku życia) mamy najbardziej dynamiczne, największe zmiany w zakresie połączeń mózgowych, w zakresie liczby komórek mózgowych. Ten okres pierwszych lat to jest okres najbardziej dynamicznych zmian, kiedy te wpływy środowiskowe mają faktycznie bardzo istotne znaczenie. Rozwój biologiczny, embrionalny jest bardzo skomplikowany. W programie rozwoju biologicznego mózgu, mamy zaszytych dużo mechanizmów, które pozwalają temu mózgowi dopasowywać się do środowiska w którym jest. Mamy wiele mechanizmów "plastyczności" dzięki którym sieci mózgowe kształtują się w odpowiedzi na doświadczenia środowiskowe i są jakoś dopasowane do tych rodzajów informacji z jakimi dany mózg, dane dziecko będzie miało do czynienia. Ten proces zaczyna się już w okresie prenatalnym. Wiemy, że już na etapie 28/29 tygodnia ciąży mózg płodu przetwarza dźwięki dochodzące do niego z "zewnątrz". Mózg może "czytać" też różne sygnały fizjologiczne (hormonalne, jak np. kortyzol - hormon stresu), bodźce dotykowe i świetlne zanim przyjdzie na świat. Noworodki dzięki doświadczeniom przed urodzeniem, mają już wykształcone preferencje dźwiękowe. Ich mózgi już są nastrojone na odpowiednie "czytanie" mowy ludzkiej, odróżnianie języka z którym miało styczność przed urodzeniem i nakierowane na głos matki. O tym wspominaliśmy w poprzedniej rozmowie: https://youtu.be/Re-ku43u2do -- prof dr hab. Ewa Haman z Wydziału Psychologii UW. Profesor prowadzi badania z zakresu psycholingwistyki rozwojowej, dotyczące wczesnego rozwoju językowego, zwłaszcza rozwoju leksykalnego, w różnych kontekstach (jednojęzycznym, wielojęzycznym).

In this discussion, we start with his pioneering work on developing susceptibility contrast for imaging perfusion while at MGH, and then his pioneering work on developing Near Infrared Spectroscopy, and using this approach to help validate fMRI contrast and shed some light on it. After this we discuss a wide range of topics that his group has been working on - falling into the categories of either methods development or mind-body interactions. He has played a major role in many insightful studies that include those using simultaneous EEG and fMRI, and looking at neuromodulation, brain plasticity, subliminal stimulation and processing, and resting state fMRI. He has been perfectly positioned and extremely active over the years to not only add to cutting edge methods and understanding of the brain, but to carry these over into eventual clinical practice.

Videos: Heather Mac Donald On How The Delusion of Diversity Destroys Our Common Humanity(11:02) This intense AI anger is exactly what experts warned of, w Elon Musk. (15:50) The FTX corruption is even worse than we thought | Redacted with Clayton Morris (13:00) Almonds can help you cut calories University of South Australia, November 20, 2022 Weight loss is never an easy nut to crack, but a handful of almonds could keep extra kilos at bay according to new research from the University of South Australia. Examining how almonds can affect appetite, researchers found that a snack of 30-50 grams of almonds could help people cut back on the number of kilojoules they consume each day. Published in the European Journal of Nutrition, the study found that people who consumed almonds – as opposed to an energy-equivalent carbohydrate snack – lowered their energy intake by 300 kilojoules (most of which came from junk food) at the subsequent meal. “Our research examined the hormones that regulate appetite, and how nuts – specifically almonds – might contribute to appetite control. We found that people who ate almonds experienced changes in their appetite-regulating hormones, and that these may have contributed to reduced food intake (by 300kJ).” The study found that people who ate almonds had 47 per cent lower C-peptide responses (which can improve insulin sensitivity and reduce the risk of developing diabetes and cardiovascular disease); and higher levels of glucose-dependent insulinotropic polypeptide (18 per cent higher), glucagon (39 per cent higher), and pancreatic polypeptide responses (44 per cent higher). Glucagon sends satiety signals to the brain, while pancreatic polypeptide slows digestion which may reduce food intake, both encouraging weight loss. “Almonds are high in protein, fibre, and unsaturated fatty acids, which may contribute to their satiating properties and help explain why fewer kilojoules were consumed.” The findings of this study show that eating almonds produce small changes to people's energy intake, Dr Carter says this may have clinical effects in the long term. Probiotics help maintain a healthy microbiome when taken with antibiotics Texas Christian University, November 18 2022. A systematic review published in the Journal of Medical Microbiology helps answer the question concerning whether probiotics should be taken along with antibiotics to support gut health. Although probiotics decrease the adverse gastrointestinal effects caused by antibiotics, their ability to preserve intestinal microbial composition that is negatively impacted by antibiotic therapy is not well understood. “Like in a human community, we need people that have different professions because we don't all know how to do every single job,” she explained. “And so, the same happens with bacteria. We need lots of different gut bacteria that know how to do different things.” While it is well known that antibiotics destroy some beneficial intestinal microorganisms, some healthcare professionals have expressed a concern that administering probiotics to antibiotic-treated patients could further alter the established gut microbe balance. The review included 29 studies published during a 7-year period. The authors concluded that consuming probiotics with antibiotics can prevent or reduce some changes caused by antibiotics to the microbiome. “When participants take antibiotics, we see several consistent changes in some bacterial species,” Dr Marroquin observed. “But when treatment was combined with probiotics, the majority of those changes were less pronounced and some changes were completely prevented.” New study shows repeated stress accelerates aging of the eye University of California, Irvine, November 21, 2022 New research from the University of California, Irvine, suggests aging is an important component of retinal ganglion cell death in glaucoma, and that novel pathways can be targeted when designing new treatments for glaucoma patients. The study was published today in Aging Cell. Along with her colleagues, Dorota Skowronska‐Krawczyk, Ph.D., at the UCI School of Medicine, describes the transcriptional and epigenetic changes happening in aging retina. The team shows how stress, such as intraocular pressure (IOP) elevation in the eye, causes retinal tissue to undergo epigenetic and transcriptional changes similar to natural aging. And, how in young retinal tissue, repetitive stress induces features of accelerated aging including the accelerated epigenetic age. Aging is a universal process that affects all cells in an organism. In the eye, it is a major risk factor for a group of neuropathies called glaucoma. Because of the increase in aging populations worldwide, current estimates show that the number of people with glaucoma (aged 40-80) will increase to over 110 million in 2040. In humans, IOP has a circadian rhythm. In healthy individuals, it oscillates typically in the 12-21 mmHg range and tends to be highest in approximately two thirds of individuals during the nocturnal period. Due to IOP fluctuations, a single IOP measurement is often insufficient to characterize the real pathology and risk of disease progression in glaucoma patients. Long-term IOP fluctuation has been reported to be a strong predictor for glaucoma progression. This new study suggests that the cumulative impact of the fluctuations of IOP is directly responsible for the aging of the tissue. Researchers now have a new tool to estimate the impact of stress and treatment on the aging status of retinal tissue, which has made these new discoveries possible. In collaboration with the Clock Foundation and Steve Horvath, Ph.D., from Altos Labs, who pioneered the development of epigenetic clocks that can measure age based on methylation changes in the DNA of tissues, it was possible for researchers to show that repetitive, mild IOP elevation can accelerate epigenetic age of the tissues. What do people experience at the border between life and death? University of London & New York University, November 20, 2022 A new study on near-death experiences featured 567 men and women whose hearts stopped while hospitalized in the United States and the United Kingdom. Out of 28 survivors of cardiac arrest interviewed as part of the study, 11 recalled memories suggesting consciousness while undergoing CPR. Additional cardiac arrest survivors provided self-reports about what they experienced while their hearts stopped. Reports included perceiving separating from their bodies and meaningful examinations of their lives. Researchers discovered spikes of brain activity up to an hour into CPR. Dr. Parnia, who served as lead investigator of the study, explained that he and the other researchers undertook this research in an attempt to scientifically explore something that health professionals have discussed anecdotally for decades: The similar stories people revived by cardiopulmonary resuscitation (CPR) often tell about the time when their hearts stopped. “For decades now, millions of people who've gone through this have reported having lucid heightened consciousness, even though from the perspective of their doctors they were not conscious and they were in death,” Dr. Parnia told MNT. The study centered around 567 men and women who received CPR after their hearts stopped beating while at one of 25 participating hospitals in the United States and the United Kingdom. When health practitioners began CPR on a patient whose heart stopped, researchers rushed to the scene, bringing along a portable electroencephalogram, or EEG, to monitor electrical activity in different parts of the brain, and near-infrared spectroscopy (NIRS) to measure oxygen saturation of superficial brain cortex regions. Taking care not to get in the way of health practitioners performing CPR, researchers also clamped a tablet computer above the patient's head. The tablet was connected to Bluetooth headphones which were placed on the patient's ears. Of 567 subjects, 213 or about 38% experienced sustained return of spontaneous circulation, meaning their pulse was restored for 20 minutes or longer. Only 53, or fewer than 10% of the participants, lived to be discharged from the hospital. Of those 53, 25 were unable to be interviewed by researchers due to poor health. The remaining 28 participants were interviewed 2 to 4 weeks after cardiac arrest depending on their recovery. Of the 28 participants interviewed, 11 — or 39% — reported having memories during cardiac arrest. Two of the 28 participants could hear the medical staff working while receiving CPR. One participant recalled seeing the medical staff working and could feel someone rubbing his chest. Using the near-death scale, six participants had transcendent experiences. Three participants reported dream-like experiences, which included a singing fisherman. Six of the 28 participants interviewed remembered the experience of dying. These recollections included one person who heard a deceased grandmother telling her to return to her body. “We characterize the testimonies that people had and were able to identify that there is a unique recalled experience of death that is different to other experiences that people may have in the hospital or elsewhere,” Dr. Parnia said, “and that these are not hallucinations, they are not illusions, they are not delusions, they are real experiences that emerge when you die.” Fifty-three participants had interpretable EEG data. Researchers discovered spikes of brain activity, including so-called gamma, delta, theta, alpha, and beta waves emerging up to 60 minutes into CPR. Some of these brain waves normally occur when people are conscious and performing functions like memory retrieval and thinking. According to the researchers, this is the first time such biomarkers of consciousness have been identified during CPR for cardiac arrest. “We found the brain electrical markers of heightened […] lucid consciousness, the same markers as you get in people who are having memory retrievals who are having […] high order cognitive processes, except that this was occurring when the brain had shut down. Research suggests agmatine can boost brain health and uplift your mood naturally Yonsei University College of Medicine (S Korea), October 28, 2022. Athletes and bodybuilders are always eager to learn more about new products that can help enhance their workouts by promoting strength and stamina. Agmatine, a natural compound, is often used by health enthusiasts as a pre-workout supplement. According to research, agmatine can also potentially be used to boost brain health and improve mood. In one scientific review, researchers suggest that the compound can help prevent neurodegenerative diseases and assist in the recovery of brain injury patients. Agmatine or 4-aminobutyl-guanidine is produced in your body from arginine, an amino acid found in foods like chickpeas, lentils, pork and poultry. When used as a pre-workout supplement, experts recommend not taking it with protein since dietary protein can slow the absorption of agmatine. This then diminishes its benefits. Agmatine is often listed on supplement labels as agmatine sulfate. Dosages range between 250 mg to 1,000 mg per scoop, with intake recommendations between one to two grams per day. Agmatine has antioxidant and anti-inflammatory effects and can scavenge harmful free radicals that cause oxidative damage to your organs and tissues. Some people believe agmatine can help enhance workouts by increasing levels of beneficial nitric oxide. This then dilates blood vessels and promotes healthy circulation. Data also suggests that agmatine may help activate the release of pain-killing, mood-lifting endorphins, which can boost motivation and mood. This suggests taking agmatine can help make you feel more inclined to exercise. The compound may also help block aged glycation end products. Your body produces these potentially carcinogenic compounds after you eat charcoal-broiled or well-done meats. Agmatine may also help down-regulate matrix metalloproteinases (MMPs), which are tissue-degrading enzymes that can facilitate the spread of malignant tumors. Studies show that agmatine works against the glutamate receptors that affect pain perception. Data from preliminary studies have supported agmatine's ability to reduce pain and strengthen the pain-killing effects of prescription opioids. Experts hope that agmatine can be used to help reduce the amount of medications needed and decrease the possibility of addiction to opioids. Supplementation with agmatine may help activate serotonin, the “feel good” chemical in your body while also decreasing levels of cortisol, the “stress” hormone that builds up when you are under duress. In a review published in the European Journal of Neuropsychopharmacology, scientists suggest that agmatine has antidepressant effects. According to a 2018 study published in the journal Human and Experimental Toxicology, agmatine can help protect brain cells from oxidative stress and inflammation caused by laboratory-induced Parkinson's. Prenatal phthalate exposure can significantly impact infant behavior and cognition, says study University of Illinois Urbana-Champaign, November 16, 2022 Prenatal exposure to phthalates, a set of chemicals commonly found in plastics and personal care products, has been shown to significantly impact aspects of behavior and cognition in infants, according to a team of researchers at the University of Illinois Urbana-Champaign. “Phthalates are widespread, and several well-known studies have reported that 100% of pregnant individuals had detectable levels of phthalates in their bodies,” said developmental neurotoxicologist Jenna Sprowles, a former postdoctoral research associate at the Beckman Institute for Advanced Science and Technology. Children's toys, cosmetics, and constructional materials are all potential sources of phthalate exposure, as are other materials made from polyvinyl chloride. When individuals who are pregnant are exposed to phthalates, the chemical compound crosses the placental barrier to interact directly with the fetus. Phthalates can also be transferred to a newborn through breast milk. Their study, reported in the journal Neurotoxicology and Teratology, investigated the neurobehavioral impacts of prenatal phthalate exposure in infants aged 4.5 and 7.5 months. Since many existing studies focus on individuals in early and middle childhood, providing attention to this age group is especially important. “Phthalates are endocrine-disrupting chemicals, meaning they interact with and alter how hormones typically act in the body. Hormones play crucial roles in brain development, so when the activities of hormones are altered by chemicals like phthalates, adverse functional effects are possible,” Sprowles said. “While we do know that different phthalates can affect different hormone systems, we don't yet know exactly how particular phthalates exert their specific effects.” The researchers found that the impact of prenatal phthalate exposure was specific to each phthalate's particular properties. For example, higher prenatal concentrations of a phthalate called MEP, which is commonly found in personal care products, were associated with lower ASQ scores (indicating below-average development) in certain domains. Their results align with existing studies, some of which have been carried out in animal models, which indicate that both prenatal and neonatal exposure to phthalates alters neural structure and function, resulting in impaired cognition and altered behavior.

Timestamps & Summary 1:47You recently participated in JEFO's annual JEFO beef Academy and presented key management and nutritional approaches to improving feed efficiency in feedlot cattle. Could you summarize what you presented during that symposium?Dr. Katie WoodA lot of my research focuses on feed efficiency and understanding feed efficiency. But in the feedlot, the aspect of gut health influences feed efficiency as well. So, if we have challenges with gut health related to rumen acidosis, and liver abscesses, certainly that is going to impact how those animals are performing and ultimately, feed to gaining in cost production for producers. My research in the feedlot looks at how we can improve gut health and improve production efficiency through those aspects.8:04I know you mentioned some other points related to feed efficiency, but I did not want to leave fecal starch in uNDF too quickly, because I am pretty sure you've done some work with some NIRS with fecal starch and that seems practical and exciting. I am wondering if you could expand on that.Dr. Katie WoodSome colleagues at University of Saskatchewan are looking at fecal measurements of using NIRS. We are familiar in the feed industry with using NIRS as a measure for nutrients, but the same can be applied to the feces as well, we just need to build some of those standardization curves. There was a paper put out with University of Lethbridge and University of Saskatchewan, where they were looking at using the NIR to measure fecal starch and it can be done easily. Some of these larger feedlots potentially that may have an NIR on farm could simply measure fecal starch right there rather than sending it out.9:56So today you would really be encouraging field gut nutritionists to make sure that they are getting a 240-hour analysis done routinely?Dr. Katie WoodIt is certainly something that we are finding, being able to more accurately predict what the growth curve will be and how those animals will perform. So, I would encourage a nutritionist to consider adding that as another analysis.11:23What are the other things that you would make sure are being looked after or considered to improve feed efficiency?Dr. Katie WoodThe other important thing is reducing stress and improving consistency. And they go hand in hand. We know that variable intake and variation can cause rumen distress and inflammation and stress to the animal. And certainly, as we introduce more stress, that impacts nutrient partitioning, and therefore growth.16:03What do you want to focus on, either in your research or in the industry on improving feed efficiency and cattle?Dr. Katie WoodOne thing I will mention is we are starting to realize that, particularly related to gut health and liver abscesses, is the longer we keep cattle on feed, and that trend towards increasing carcass weights, we know that's the end period, where we even start to see a little bit of decrease in performance of those animals. It is also a time period where we see increased risk of acidosis as opposed to earlier in the feeding period. And we know these cattle are heavy, we know that they are highly stressed, sometimes because of that weight. Sometimes we have some challenges with some feet issues. And we think that there could be some implications, again, related to insulin insensitivity and Energy Commission as well.20:12Is there any other points you'd like to stress when it comes to managing and improving feed efficiency and cattle?Dr. Katie WoodCertainly. Talking about that receiving period, which is kind of one of the higher risk time periods, you have cattle coming from all different sources, they may have been shipped across the country. So, do not forget about treating those receiving cattle well, because we know that it pays off in the long term. We do not have a good handle on how much that impacts the feed conversion over the rest of the feeding period. But certainly, we know, related to illness, it has a huge effect.

The gold standard for estimation of the cerebral infarction volume is magnetic resonance imaging (MRI), which is expensive and not readily accessible. Measuring regional cerebral blood flow (rCBF) with Laser Doppler flowmetry (LDF) is the status quo for confirming reduced blood flow in experimental ischemic stroke models. However, rCBF reduction following cerebral artery occlusion often does not correlate with subsequent infarct volume. In the present study, we employed the continuous-wave near infrared spectroscopy (NIRS) technique to monitor cerebral oxygenation during 90 min of the intraluminal middle cerebral artery occlusion (MCAO) in Sprague-Dawley rats (n=8, male). The NIRS device consisted of a controller module and an optical sensor with two LED light sources and two photodiodes making up two parallel channels for monitoring left and right cerebral hemispheres. Optical intensity measurements were converted to deoxyhemoglobin (Hb) and oxyhemoglobin (HbO2) changes relative to a 2-min window prior to MCAO. Area under the curve (auc) for Hb and HbO2 was calculated for the 90-min occlusion period for each hemisphere (ipsilateral and contralateral). To obtain a measure of total ischemia, auc of the contralateral side was subtracted from the ipsilateral side resulting in {Delta}Hb and {Delta}HbO2 parameters. Infarct volume (IV) was calculated by triphenyl tetrazolium chloride (TTC) staining at 24h reperfusion. Results showed a significant negative correlation (r = -0.81, p = 0.03) between {Delta}Hb and infarct volume. In conclusion, our results show feasibility of using a noninvasive optical imaging instrument, namely NIRS, in monitoring cerebral ischemia in a rodent stroke model. This cost-effective, non-invasive technique may improve the rigor of experimental models of ischemic stroke by enabling in vivo longitudinal assessment of cerebral oxygenation and ischemic injury.

Joe DeMare talks about his experiences hanging out with atlatl throwers and flint knappers at the beautiful Letchworth State Park in New York. Then he talks with Diane D'Arrigo of NIRS about a threat to New York, Ohio, PA, and Canada from improper demolition of the nuclear waste reprocessing building in West Valley. Rebecca would tells us how flint is formed and the difference between concretions and nodules. Ecological News includes some really bad news about nuclear and some really good news about wind and solar.

The Wisconsin Retirement System (WRS) was created 40 years ago to help protect public employees and their beneficiaries against the financial hardships of old age and disability, to attract and retain a qualified public workforce, establish modest benefits, and achieve administrative savings. There is no doubt that the WRS has done that and more over the last four decades. But, the WRS, as one of the only fully funded public pension systems in the country, is more than just a retirement benefit for state and local government employees. It also provides a strong, steady economic pillar for the entire state. Economic gains attributable to defined benefit pensions like the WRS are substantial. Benefits paid by state and local pension plans support a significant amount of economic activity that ripples through the economy, creating a multiplier effect as one person's spending becomes another person's income. In Wisconsin, more than 85% of WRS pensions go to retirees living in Wisconsin who purchase goods and services and pay taxes. In this episode, we talk to Dan Doonan, executive director of the National Institute on Retirement Security, a non-profit research and education organization established to contribute to informed policymaking by fostering a deep understanding of the value of retirement security to employees, employers, and the economy as a whole. Dan shares some insights about what he calls "Pensionomics," and some recent studies his organization has conducted that show just how crucial the WRS and other defined benefit plans like it are to their local economic ecosystems.
Near infrared spectroscopy (NIRS) ... 'a variation of pulse oximetry; it transmits red and infrared light into tissue' measures information from arterial venous and capillary blood simultaneously to deduce tissue saturation; an aggregate estimate of arteriovenous capillary blood and whatever tissue you're shining the light into. 'So typically, we're using it in on the brain at least in the cardiac and vascular space, but people also in other areas like the surgical ICU, can use it to measure muscle oxygenation as well'. Learn how this technique could enhance your practice, what its potential for advancement is and where its limits lie. This piece is likely to be of critical interest to most cardiac surgeons and those who work alongside them. This piece was generously supported and brought to you by Medtronic. Presented by Desiree Chappell and Monty Mythen with their guests Robert Thiele, Cardiac Anesthesiologist and Intensivist at the University of Virginia, Carol Ann Rosenberg, Associate Director of Perfusion and ECMO, Kenan Yount, Cardiac Surgeon and Director of the Valve center and Director of the Aortic Center at the University of Virginia.
