The neural circuits that control eye movements are complex and distributed in brainstem, basal ganglia, cerebellum, and multiple areas of cortex. The anatomical function of the substrates implicated in eye movements has been studied for decades in numerous countries, laboratories, and clinics. The modest goal of this brief review is twofold. (1) To present a focused overview of the knowledge about the role of the cerebral cortex in voluntary control of eye movements. (2) To very briefly mention two findings showing that the accepted hierarchy between the frontal and the occipital sensory areas involved in sensory-motor transformation might not be so trivial to reconcile, and to interpret in the context of eye movement command. This presentation has been part of the 44th Cambridge Ophthalmological Symposium, on ocular motility, 3 September 2014 to 5 November 2014.
控制眼球运动的神经回路十分复杂,分布于脑干、基底神经节、小脑以及多个皮质区域。数十年来,众多国家、实验室和诊所都对与眼球运动相关的神经基质的解剖功能进行了研究。这篇简短综述的适度目标有两个。(1)集中概述有关大脑皮质在眼球运动自主控制中作用的知识。(2)简要提及两项研究结果,这两项结果表明,参与感觉运动转换的额叶和枕叶感觉区域之间公认的层级关系,可能并非那么容易调和,并结合眼球运动指令进行解读。本报告是2014年9月3日至11月5日举行的第44届剑桥眼科学研讨会关于眼球运动部分的内容。
