Stanford professor Robert Sapolsky lectures on depression as a real biological disease. He covers its biological and psychological causes, how it differs from ordinary sadness, and ideas such as learned helplessness. He ties these together into one account.

Michael Levin's NeurIPS 2018 talk on bioelectric computation outside the nervous system, showing how cell electrical networks shape development and regeneration. It covers morphological information processing in living tissue.

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.

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.

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.

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.

The Thought Emporium grows living rat neurons on an electrode array and tries to train them to play Doom. It is part of a series on biological computing.

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.

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.

A dialogue with Gary Weber on the default mode network, meditation and non-dual awakening, with discussion of psychedelics, thought and time. It is part of the Non-Dual Couch series.

Sebastian Seung's TED talk introduces the connectome, the map of neural connections he argues defines each person. He explains how mapping it could change how we understand brains and minds.

David Rock gives a Google Tech Talk based on his book Your Brain at Work, using neuroscience to explain why focus and productivity are hard at the office. He gives strategies for managing mental energy and distraction.

Neurologist Dr. Matthew Phillips talks at Low Carb Gold Coast 2022 about fasting and ketogenic diets as therapies for cancer and neurodegenerative disease. He focuses on mitochondrial dysfunction and brain energy metabolism.
