A Google Tech Talk by sleep researcher Dr. William Dement on healthy sleep and performance. He argues sleep debt must be repaid and describes the three characteristics of healthy sleep.

Joe Rogan interviews Matthew Walker, Berkeley neuroscience professor and author of Why We Sleep. They discuss what sleep does for the brain and body, the effects of sleep deprivation, and sleep myths.

Andrew Huberman's podcast episode on what makes us sleepy, helps us sleep soundly and keeps us alert. It lays out the science and a set of behavioral tools such as light timing.

CGP Grey explains split-brain patients, where severing the corpus callosum lets the two hemispheres act independently. He uses this to explore the idea of two minds in one head.

A two-hour Huberman Lab podcast episode on the physiological effects of alcohol on the brain and body at different levels of consumption. It covers genetic predisposition to alcoholism, alcohol metabolism, and how it causes cellular stress and changes thinking and behavior.

Robert Sapolsky's lecture on how the body's stress response, evolved for short-term physical emergencies, harms long-term health when triggered by psychological stressors. It was given as the inaugural Fenton-Rhodes Lecture.

Destin Sandlin of Smarter Every Day undergoes hypoxia training and experiences his own impaired thinking as oxygen is withdrawn. The video shows how quickly and unnoticeably oxygen deprivation degrades judgment, illustrating why you put your own mask on first.

Neuroscientist Anil Seth gives a Royal Institution lecture on the science of consciousness. He separates conscious level, content and self, and argues that experience arises from the brain's predictive inference.

Andrew, diagnosed with early onset Parkinson's at 35, shows how deep brain stimulation surgery has controlled his motor symptoms. The short video shows his tremors with the stimulator off and on.

Adam Neely explains what perfect (absolute) pitch is, how it differs from relative and quasi-absolute pitch, and why he would not want it. He covers its drawbacks, including drift with age.

Dr. Howard Schubiner presents his research that much chronic pain comes from learned neural pathways rather than structural damage, and outlines a treatment approach based on that view.

Rick Beato argues that adults cannot develop true perfect pitch, which he ties to critical-period brain plasticity and language acquisition. He says it can only be developed in young children, and discusses the research behind this.

Destin of Smarter Every Day learns to ride a bicycle whose steering is reversed, taking about eight months, and compares it with how his young son learned much faster. It illustrates knowledge versus understanding and brain plasticity in adults versus children.

A NOVA documentary with neuroscientist Heather Berlin exploring the subconscious and what drives our decisions. It uses sleepwalking, anesthesia, improvised rap in an MRI and game theory to probe how much of the brain's work is hidden.

A Huberman Lab podcast episode on the gut-brain axis and how the gut microbiome affects the nervous system, hunger and overall health. It covers the pathways by which the gut influences the brain and practical steps for gut health.

A 73-minute Stanford talk by Robert Sapolsky drawn from his book Behave. It surveys the biological factors behind human behavior at its best and worst.

Robert Sapolsky's Stanford lecture on language, comparing human and animal communication, ape language projects like Koko and Kanzi, and how language is acquired. It is part of his human behavioral biology course.

Neuroscientist Jill Bolte Taylor describes watching her own brain functions shut down during a massive stroke. She gives a first-person account of losing speech, motion and self-awareness.

An RSA Animate summary of Iain McGilchrist's lecture on the divided brain, arguing the brain's two hemispheres attend to the world differently and that this has shaped culture and society.

Cognitive scientist Donald Hoffman argues in this TED talk that evolution shaped perception to track fitness rather than truth. He uses evolutionary simulations and the Australian jewel beetle as examples.

Dr. Russell Barkley lectures on the neuroanatomy of ADHD and how to treat it, linking executive function and working memory to the disorder. It is part 3 of a CADDAC series.

The original invisible gorilla awareness test by Daniel Simons and Christopher Chabris, in which viewers count basketball passes and often miss a gorilla crossing the scene. It demonstrates inattentional blindness.

A roughly 10-minute guided Non-Sleep Deep Rest session voiced by neuroscientist Andrew Huberman. It is meant to reduce daytime fatigue, improve focus and aid sleep.

Veritasium explores why time seems to speed up as we age, covering chronoception and several competing explanations beyond the common proportional-theory argument.

Berkeley sleep scientist Matthew Walker presents the science of sleep and dreams and how sleep affects health and lifespan, based on his book Why We Sleep.
