Oliver Sacks is the best-selling author of many books about the mysteries and marvels of the human mind, including “Hallucinations,” his 12th, which explores the various ways in which we may viscerally experience worlds that, ultimately, do not exist. The New York Times once dubbed Mr. Sacks “the poet laureate of medicine.” (BBC via Associated Press)
