Abstract

Magnetic source imaging revealed that the topographic representation in the somatosensory cortex of the face area in upper extremity amputees was shifted an average of 1.5 cm toward the area that would normally receive input from the now absent nerves supplying the hand and fingers. Observed alterations provide evidence for extensive plastic reorganization in the adult human cortex following nervous system injury, but they are not a sufficient cause of the phantom phenomenon termed 'facial remapping'.
