WE studied a patient after amputation of an arm and found that in less than 24 h stimuli
applied on the ipsilateral face were referred in a precise, topographically organized,
modality-specific manner to distinct points on the phantom. Functional magnetic resonance
imaging (fMRI) performed one month later showed that brush-evoked activity in the brain
demonstrates objective signal changes which correlate with perceptual changes in the
phantom hand. This finding in humans corresponds to the observations of immediate …
