The Real Reason Your Brain Makes You Dream Every Night | Dr. David Eagleman
Dr. David Eagleman is a Stanford neuroscientist, author, and host of the Intercosmos podcast. He explains why your brain is a team of rivals and not one single you. He covers why time seems to slow down in a crash, and why dreams exist at all. His theory is that dreaming protects your visual cortex from being taken over by the other senses.
He also talks about brain-computer interfaces, new senses for deaf people, and rehabilitation over punishment in the courts. He gets into sleepwalking murders, lucid dreaming, Alzheimer's, psychics, and the biggest open mystery in neuroscience: consciousness. The episode ends with audience Q&A from the live room.
