This book follows the life of an influential neuropsychologist's varied career. It features coverage of research into human evolution, archaeology and neurology. Beginning with his earliest memories (and implications for memory processes), the author reflects on his archaeological expeditions preceding his primary career as a physiological psychologist and a behavioural neuroscientist. His influential research covers such rare neurological disorders as Huntington's disease, Friedreich ataxia and Williams syndrome, and more common maladies like Parkinson's and Alzheimer's diseases, stroke, Fragile X, Tourette's syndrome, obsessive compulsive and attention deficit hyperactivity disorders, schizophrenia, autism and depression.
