Amputees’ brains remember missing hands even years later | ScienceDaily

Our brains have a detailed picture of our hands and fingers, and that persists even decades after an amputation, Oxford University researchers have found. The finding could have implications for the control of next generation prosthetics.

Team leader, Dr. Tamar Makin said: ‘It has been thought that the hand ‘picture’ in the brain, located in the primary somatosensory cortex, could only be maintained by regular sensory input from the hand. In fact, textbooks teach that the ‘picture’ will be ‘overwritten’ if its primary input stops.
