Abstract

Units of the caudate and putamen were studied during stereotactic operations in II patients with movement disorders. Responses of these units to different visual stimuli were found for cells of the caudate nucleus head. These units were activated mainly during the presentation of nutritional stimuli. The responses appeared when a slide was shown presenting an image of drink or food or the corresponding word. Frequently the same unit was activated by slides of the image and the word presented in succession. Responses to similar stimulations were not observed in the putamen. Among the parkinsonian patients, only those with tremor had responsive cells while the rigid patients had not. This discrepancy was correlated with the lowering of cortical metabolism demonstrated by PET scan in the rigid group of patients. These results are in agreement with those obtained in monkeys during food presentation. They present, moreover, the advantage of showing that these responses could be provoked in man by more abstract stimuli, not only the image but the name of the object. These observations do not imply a long testing period; 2 or 3 cells only are studied in each patient. They have the advantage for the patient of ascertainting the position of the trajectory in the striate structure, in the same way as thalamic nuclei are delineated using other types of stimuli. Moreover, it is of interest interest to have a better knowledge of the behavioral role played bydifferent striatal regions at a time when lesions or stimulations at this level are proposed to cure abnormal movements in human.
