Ramachandran showed that this syndrome occurs due to reorganization of the postcentral gyrus, which contains the S1 somatosensory cortex, in a classic example of neural plasticity.
A key insight into this condition came from Timothy Pons's research on the fluidity of the Penfield map, which was conducted on a group of 12 chimpanzees that had suffered denervation during a previous experiment. The neuromatrix theory, proposed by Ronald Melzack, was an attempt to explain this disorder, which was originally explained by the formation of neuromas by irritation. VS Ramachandran showed that this syndrome occurs due to reorganization of the postcentral gyrus, which contains the S1 somatosensory cortex, in a classic example of neural plasticity. It can be treated by using a mirror-box, so that the brain is tricked by a mirror image. This condition most commonly occurs in amputees. For 10 points, name this syndrome in which a missing part of the body is still believed to be there.
