Phantom Limb Syndromes
Introduction
Most people who have had amputation would have experienced a phantom limb; it is a sensation that the limb is actually present, and in some cases there is a feeling of pain. There is a lot of empirical evidence to suggest changes in cortical topography following amputation. “With the advent of non-invasive imaging techniques such as MEG (magneto encephalogram) and functional MRI, topographical reorganization can also be demonstrated in humans, so that it is now possible to track perceptual changes and changes in cortical topography, in individual patients.”
A feature of the human brain is the multiplicity of specialized areas, ...
