Oliver Sacks on Hallucinations

Neurologist Oliver Sacks talks about hallucinations, which can be linked to sensory deprivation, intoxication, illness, or injury. His new book, Hallucinations, weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organization and structure of our brains, how they have influenced every culture’s folklore and art, and why the potential for hallucination is present in us all, a vital part of the human condition.
