摘　　要：航天飞行初期,空间运动病、空间定向障碍一直是航天医学界的重要难题,而两者的发生机制均与视觉和前庭觉有着紧密的联系。如今视觉刺激、前庭刺激对脑高级认知功能影响的研究已展开,但视-前庭联合刺激下对脑高级认知功能影响的研究,还处于探索阶段。目前认知有关的研究手段有很多,其中具有毫秒级时间分辨率的脑事件相关电位(event-related potentials,ERPs)是一种较为客观且简便易行的研究方法。本文综述了视觉、前庭觉与脑高级功能联系的解剖学基础,介绍了采用ERP为研究手段的部分视觉认知研究动态以及视-前庭相互作用对脑高级功能影响的研究现状,提出了今后的研究方向,为今后开展该方面研究提供了参考。In the early days of space flight,space motion sickness and spatial disorientation were always essential medical problems in space medicine.Either of them was closely connected with visual and vestibular system in its development.Nowadays some progresses were made in the researches about brain cognitive function changes during visual or vestibular stimulation,but the effects of visual-vestibular interaction on the brain cognitive processing are still under exploration.Lots of research techniques have been used in cognitive explorations,the brain event-related potentials（ERP） with its high time resolution is an objective and convenient means.In this article,the anatomic bases of visual,vestibular system and their projection to cortex,research progresses in visual cognition explored with ERP and current phenomena about the effects of visual-vestibular interaction on brain cognitive processing were reviewed.Research directions about visual-vestibular interaction on cognitive processing were put forward in order to provide reference for future studies.
