excerpt:"Neurologist and writer Oliver Sacks has spent his career examining patients struggling to survive with a wide range of neurological conditions: Tourette's syndrome, autism, Parkinson's, musical hallucinations, Alzheimer's disease and phantom-limb syndrome.
But in his latest book, The Mind's Eye, Sacks turns the tables on himself. He writes about being diagnosed with a rare eye tumor and the subsequent total loss of vision on his right side. He also shares the case studies of other people who learned to compensate and adapt after neurological disorders robbed them of their ability to recognize faces, read or see.
Sacks tells Terry Gross that since the loss of half of his vision — and by extension, his stereoscopic vision — he has had to learn to adapt to a world that appears to be entirely flat.
