If so, then no one has supplied more theories and findings to fill that hole than Ramachandran. The Cartesian division of mind and body long ago fell out of fashion in both philosophy and neuropsychology, but only recently have we begun to realise that not only is the brain part of the body but the body is also part of the brain. Ramachandran has been at the forefront of reimagining this interdependence with his ground-breaking work on phantom limbs.
Among amputees, 90% suffer from phantom limb pain, which can often cause excruciating discomfort. For most of the 20th century, medical science was divided over whether the cause was psychological or as a result of traumatised nerve endings. Neither hypothesis did much to help the afflicted.
