A Neurologist Has "A Leg to Stand On"

Neurologist and writer Oliver Sacks, whose book of case studies, The Man Who Mistook His Wife for a Hat, has been made into a music theater production. Sacks is also the author of Awakenings, a work about victims of sleeping sickness, to whom he administered the experimental drug L-dopa.

The famed neurologist talks to Fresh Air about how grief, trauma, brain injury, medications and neurological disorders can trigger hallucinations — and about his personal experimentation with hallucinogenic drugs in the 1960s.

Neurologist Oliver Sacks is famous for his case studies of people with neurological disorders that cause unusual problems with perception. In The Mind's Eye, Sacks turns to himself, explaining how an eye tumor affected his vision and perception of the world.
