As part of their “TED Q & A” series, Wired published an interview with Neurologist Oliver Sacks where he discusses visual hallucination and his experiences after losing central vision in his right eye.

To compensate for the missing visual data once supplied by his right eye, his brain has projected hallucinations and patterns onto the dark stage -– a phenomenon common to people who have lost their sight. Ever curious about the mind’s varied responses to disease, Sacks has chronicled it all in a series of unpublished journals containing drawings and writings.

Last year at the Technology Entertainment and Design conference, one of the most popular talks was given by Jill Bolte Taylor, a neuroanatomist who described what occurred in her mind and body as she experienced a stroke.
