TED Talks has posted a video of neurologist Oliver Sacks discussing hallucinations — particularly Charles Bonnet hallucinations, which occur among many visually-impaired people.
Oliver Sacks is known for his investigation of neurological disorders that result in bizarre experiences and behavior. One of Sacks’s early books was calledAwakenings, which was made into a movie of the same name, with Robin Williams playing a doctor based on Sacks, and Robert Deniro playing a catatonic patient who ‘comes back to life’ through an experimental treatment.
Some of my favorite Sacks books are The Man Who Mistook His Wife for a Hat andAn Anthropologist on Mars. Sacks is a great writer, and his books are very entertaining as well as informative.
The video is about 18 minutes — see “Oliver Sacks: What Hallucination Reveals About Our Minds.”
