title: Ocular motor dysfunction in total and hemicerebellectomized monkeys.
abstract: Studies of ocular motor function in monkeys undergoing either total or hemicerebellectomies has revealed the following abnormalities which can be attributed to cerebellar dysfunction: 1. Loss of smooth pursuit movements 2. Gaze-fixation nystagmus 3. Loss of inhibitory input on the vestibular apparatus reflected in a decreased latency and prolonged response to caloric stimuli. It is intimated that the role of the hemicerebellum deals with ipsilateral tone and its effect on eye movements.
