We report the results of serial transcranial magnetic
stimulation mapping of cortical motor outputs to the face and upper
extremity in a subject studied before and repeatedly after traumatic
amputation of the right arm immediately below the elbow. The results
of the mapping studies illustrate the time course of plastic changes
in the motor cortical representation in humans following a traumatic
amputation and allow the correlation of subjective perceptions of phantom
limbs with the reorganization of cortical outputs.
