In The Mind’s Eye, physician and author Oliver Sacks tells the stories of people who are able to navigate the world and communicate with others despite losing what many of us consider indispensable senses and abilities: the power of speech, the capacity to recognize faces, the sense of three-dimensional space, the ability to read, or the sense of sight. Dr. Sacks recently visited the American Museum of Natural History to discuss his book and how he too has struggled with several perceptual conditions, from face-blindness to a loss of stereo vision due to ocular cancer. Dr. Sacks’ talk was recorded live on Oct. 17, 2011.
