前庭信号在空间定向、物体位置感知和自我运动控制中起着重要作用。先前关于前庭信息处理的生理学研究主要集中在脑干机制上;相对而言，对大脑皮层水平的前庭信息处理知之甚少。最近的电生理实验研究使用前庭通道信号在两个不同的感知任务：计算的自我运动和本地化的视觉刺激在一个以世界为中心的参考系。这两种知觉功能由后顶叶皮层的不同部分介导，前一部分在内侧上级颞区（MSTd）的背侧，后一部分在7a区。
Vestibular signals play an important role in spatial orientation, perception of object location, and control of self-motion. Prior physiological research on vestibular information processing has focused on brainstem mechanisms; relatively little is known about the processing of vestibular information at the level, of the cerebral cortex. Recent electrophysiological experiments examining the use of vestibular canal signals in two different perceptual tasks are described: computation of self motion and localization of visual stimuli in a world-centered reference frame. These two perceptual functions are mediated by different parts of the posterior parietal cortex, the former in the dorsal aspect of the medial superior temporal area (MSTd) and the latter in area 7a.
