Professor Diamond begins this lecture with her famous discussion of the human brain, demonstrating her favorite subject with a preserved sample. She then launches into a discussion of the muscular system, starting with its general functions: movement, support, heat generation, facial expression, and protection. She discusses nomenclature for muscles and how these are impacted by the number of muscle heads, the muscle length, muscle locat...more

Karl Deisseroth is pioneering bold new treatments for depression and other psychiatric diseases. By sending pulses of light into the brain, Deisseroth can control neural activity with remarkable precision. In this short talk, Deisseroth gives an thoughtful and awe-inspiring overview of his Stanford University lab's groundbreaking research in "optogenetics".

How billions of interconnected cells in the brain can interpret and regulate all our bodily functions as well as mediate our experiences of interactions with and responses to the world around us is a huge and fascinating question that many different disciplines have attempted to tackle. This lecture will consider what we have learned so far about the principles of neural encoding and how they may begin to explain our memories, emotions...more

Kwabena Boahen is using the human brain as the blueprint for designing radically more powerful and energy-efficient computers. In this short demo, Boahen describes how his Brains in Silicon lab at Stanford University has created computer chips with "synapses" and "neurons" -- and how these chips might revolutionize computing.

Krishna Shenoy is creating "brain-computer interfaces" that will enable paralyzed patients to control prosthetic arms and computer cursors. In this short talk, Shenoy describes how his team of Stanford researchers has built a system that achieves typing at 15 words-per-minute, just by "thinking about it".

This lecture introduces students to two broad theories of how the mind relates to the body. Dualism is the ubiquitous and intuitive feeling that our conscious mind is separate from our physical bodies, whereas Materialism is the idea that all of our mental states are caused by physical states of the brain. This lecture reviews arguments explaining why materialism has become the predominant theory of mind in psychology. This discussion is f...more

Jennifer Raymond (Stanford University) is building a "wiring diagram" for the brain. By bridging the gap between individual synapses and whole-brain learning & memory, Raymond's research offers new insights and strategies for medical rehabilitation and K-12 education.

Loss of sensory or behavioural functions as a result of brain damage or dysfunction can clearly have a significant negative impact on quality of life. What progress are we making towards repairing damaged brains and sense organs and treating mental disorders? This lecture will consider what therapeutic promise is currently offered by pharamacological, brain stimulation, brain training, neuroprosthetic (connecting artificial sensors to...more
