In this study, we wish to find behavioral evidence for the question whether an amputation of the arm can lead to changes in visual perception or motor responses to objects in peripersonal space. We hypothesize that changes in the motor and somatosensory hand-related cortices following amputation might lead to changes in parietal hand-related areas. The consequence of these parietal changes should be reflected behaviorally in reduced perception/attention/responses to hand-related objects in the space ipsilateral to the amputation. We further hypothesize that the use of prosthetics may provide the necessary visual feedback to maintain an intact hand representation and therefore lead to lesser cortical reorganization in both visual and somatosensory cortical areas.
