Guiding effective movement through the environment is one of the visual system's most important functions. The pattern of motion that we see allows us to estimate our heading accurately in a variety of environments, despite the added difficulty imposed by our own eye and head movements. The cortical substrates for heading perception include the medial superior temporal area (MST) and the ventral intraparietal area (VIP). This review discusses recent work on these two areas in the context of behavioral observations that establish the important problems the visual system must solve. Signals relevant to self motion are both more widespread than heretofore recognized and also more complex because they are multiplexed with other sensory signals, such as vestibular, auditory, and tactile information. The review presents recent work as a background to highlight important problems that remain unsolved.

自我运动知觉的机制。

引导环境中的有效运动是视觉系统最重要的功能之一。尽管我们自己的眼睛和头部运动增加了难度，但我们看到的运动模式使我们能够在各种环境中准确地估计航向。用于航向感知的皮质基质包括内侧颞上区（MST）和腹顶腹内区（VIP）。这篇综述在行为观察的背景下讨论了这两个领域的最新工作，这些行为建立了视觉系统必须解决的重要问题。与自我运动有关的信号不仅比以前认识到的要广泛，而且也更复杂，因为它们与其他感觉信号（例如前庭，听觉和触觉信息）复用。
