"Since his book Awakenings first stormed the bestseller lists (and subsequently the silver screen), Oliver Sacks has become an unlikely household name - a pioneer in the field of neurological anthropology as well as an engaging storyteller. In this TEDTalk, he brings our attention to Charles Bonnet syndrome - a hallucinatory disorder that sometimes afflicts the visually impaired. Sacks describes the experiences of his patients in detail and walks us through the physiology of this under-reported phenomenon." . "TED Talks" .
