This week, we’re honoring the memory of Oliver Sacks, esteemed neurologist and author of numerous bestselling books, including “Awakenings”, “The Man Who Mistook His Wife for a Hat,” and, most recently, his autobiography “On the Move.” We’re reaching back in the archives to 2009, when Dr. Sacks delivered NYPL’s annual Robert B. Silvers lecture. In this fascinating talk, Dr. Sacks explores the musical hallucinations of the deaf, the visual hallucinations of the blind, and more strange behaviors of the human brain.
