"What causes the startling, unbidden perception of something that seems very real but has no material existence outside of our own minds? The “poet-laureate of medicine,” Oliver Sacks, takes us through the looking glass and into the fascinating world of hallucinations. Oliver Sacks, MD, is a physician, best-selling author, and professor of neurology at the NYU School of Medicine. He is best known for his collections of neurological case histories, including The Man Who Mistook His Wife for a Hat (1985), An Anthropologist on Mars (1995),Musicophilia: Tales of Music and the Brain (2007), and The Mind’s Eye (2010). His bookAwakenings (1973) inspired the 1990 Academy Award-nominated feature film starring Robert De Niro and Robin Williams. Sacks is a frequent contributor to the New Yorker and the New York Review of Books and a fellow of the American Academy of Arts and Sciences. His newest book is Hallucinations (2012)."
