Eye movement control by Purkinje cell/climbing fiber zones of cerebellar flocculus in cat.
Direction of eye movement evoked by unilateral stimulation of the cerebellar flocculus was investigated by a video system with frame memory in ketamine-anesthetized cats. Stimulation of the Purkinje cell zone in the vertical-plane unit on the right side evoked depression of both eyes combined with intorsion of the contralateral eye and extorsion of the ipsilateral eye, and stimulation in the horizontal-plane unit evoked abduction of the ipsilateral eye and adduction of the contralateral eye.
