Abstract

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.

摘要

通过带有帧存储器的视频系统，在氯胺酮麻醉的猫身上研究了单侧刺激小脑绒球所诱发的眼球运动方向。刺激右侧垂直平面单元中的浦肯野细胞区会诱发双眼下视，同时对侧眼内旋、同侧眼外旋；刺激水平平面单元会诱发同侧眼外展和对侧眼内收。
