This report concerns the effects on ocular movements from stimulation of the paramedian region of the depths of the cerebellum and the dentate nucleus. Stimulation in the region of the dentate nucleus of the cerebellum resulted in ipsilateral eye movements. Activation of the cerebellum also resulted in nystagmoid movements and a subjective feeling of dizziness. After a lesion in the same region, the head and eyes were deviated contralaterally and the patient was unable to look toward the side of the lesion. The ocular defects resulting from stereotactic lesions in the depths of the cerebellum were transient.
