Hawkins is working on his third start-up. Besides starting Palm and Handspring, Hawkins also followed his passion for theoretical neuroscience, the study of how certain parts of the brain work from an information theory point of view. He started a non-profit research institute called the Redwood NeuroScience Institute. Through this experience, he learned that starting a non-profit is just like starting a business.

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

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.

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

Not quite a brain teaser but fun nonetheless!

Fun word problem that is almost a brain teaser.

Just how near are we to using our brains routinely to control machines for work or leisure purposes? Will we be able to improve the performance of our existing brains? Have advances in neuroscience, neural network modelling and the physical sciences led us to the point where it could soon be possible to create artificial, nanoscale brains and where might such technology lead us?

How hormones, phermones and bonding chemicals connect with the experiences of sexual arousal and romantic love. To what extent are we victims of our brain chemistry and neural processes? What are the evolutionary origins and adaptive values of "falling in love"?

The visual system has developed to allow us to navigate in a complex and dangerous world in order to find food and to avoid danger. This survival system works by building a complex three-dimensional model based on two-dimensional data from the retina. This model is tested against "reality" and checked with information from other senses and updated if needed. The brain suppresses the complexity of this processing and we believe that visi...more

In this lecture, Katie Brakora, the head GSI, introduces the course and the required texts and discusses strategies for success in studying human anatomy. She encourages students to take a systemic view of human anatomy, understanding systems in whole and in part, rather than focusing on memorizing terms. After this introduction, Brakora discusses the attributes of the human brain using a preserved sample. Then, Brakora surveys the hist...more

In this lecture on the male reproductive system, Professor Diamond begins by covering the primary sex organ (the gonad or testis). She discusses its function in producing sperm and testosterone, location within the male body, and the reason it is enclosed in a separate pouch called the scrotum (temperature regulation by the eremasteric muscle). Then she talks about the source of sperm, structure of the testis, in particular, the lobules, s...more

Professor Diamond continues her discussion of the nervous system with a diagram of a cross section of a developing spinal cord in which she highlights the ependyma, the mantle layer, the neuronal soma, and the marginal layer. She compares the developing cord to an adult cord and discusses the ventricles, the posterior and anterior horn, and the lateral horn in the thoracic cord. After relating these to the sympathetic division of the autom...more
