pubmed:abstractText |
Unilateral lesions of the substantia nigra were performed on baboons which had been previously trained to perform a visual pointing movement. The resulting motor impairment consisted of an increase in movement duration. This bradykinesia shows as a regular decrease in velocity. A possible change in mode of motor control caused by lesion of the SN is discussed. Partial exclusion of SN might bring about a shift from the feedforward to a feedback mode relaying more heavily on visual cues.
