Physiological Study of the Pallidal Neurons in Parkinson’s Disease
Although our understanding of the human basal ganglia (BG) is still relatively poor, the old type of pallidotomy (Svennilson et al., 1960: Narabayashi et al., 1956) is now modified and the revised type of pallidotomy has been widely accepted and its clinical benefit seems to be favorable to some extent (Sutton et al., 1995: Laitinen et al., 1992). Therefore, to elucidate the pathophysiological state of BG, particularly the internal segment of the globus pallidus (GPi), depth electrode recording during the course of stereotactic surgery as we have been using during thalamotomy for movement disorders, might also be useful.
