视觉空间如何在大脑中表征是神经科学中的一个悬而未决的问题。具身性理论认为空间知觉是由神经运动映射构成的。特别是，编码扫视眼球运动的目标的地图包含外部空间的精确表示。在这篇评论文章中，我们研究如何修改眼跳地图是伴随着视觉空间感知的变化。眼跳适应是一种系统地调整眼跳幅度，改变视觉对象在空间中的定位的方法。我们说明如何扫视幅度的信息是从小脑（CB）转移到额叶眼场（FEF）。我们认为，适应眼跳地图后，视觉定位的变化提供了证据，视觉和运动空间的共享表示。
How visual space is represented in the brain is an open question in neuroscience. Embodiment theories propose that spatial perception is structured by neural motor maps. Especially, maps which code the targets for saccadic eye movements contain a precise representation of external space. In this review article, we examine how modifications in saccade maps are accompanied by changes in visual space perception. Saccade adaptation, a method which systematically modifies saccade amplitudes, alters the localization of visual objects in space. We illustrate how information about saccade amplitudes is transferred from the cerebellum (CB) to the frontal eye field (FEF). We argue that changes in visual localization after adaptation of saccade maps provide evidence for a shared representation of visual and motor space.
