Cortical areas were explored with regard to saccade control: the lateral intraparietal (LIP) area is involved in the spatial aspects of sensorimotor processing; the supplementary motor area in goal-directed gaze control; and from lesion studies; the posterior parietal cortex in triggering visually guided saccades. Different studies have suggested that the spatial-to-temporal transformation takes place in the superior colliculus (SC) and the cerebellum. When the vestibulo-ocular reflex (VOR) produces inadequate eye movements, other supplementary mechanisms (e.g. non-visual, saccade) may play a role in correcting gaze. A classification of central vestibular disorders of the brainstem and VOR has been proposed, as manifested in any one of the three major planes of action (yaw, pitch and role).
顶内沟外侧（LIP）区域参与感觉运动处理的空间方面；辅助运动区参与目标导向的注视控制；从病变研究来看，后顶叶皮质参与触发视觉引导的扫视。不同的研究表明，空间到时间的转换发生在上丘（SC）和小脑。当前庭眼反射（VOR）产生的眼球运动不足时，其他辅助机制（如非视觉、扫视）可能在纠正注视中发挥作用。已经提出了脑干和VOR中枢前庭障碍的分类，表现为三个主要作用平面（偏航、俯仰和滚动）中的任何一个。
