视觉运动系统最重要的两个感知功能是计算我们在环境中移动时的前进方向，并根据运动线索推断出物体和环境的三维结构。下面，我们回顾一些实验，这些实验提供了关于大脑如何构建这些感知现象的见解。了解运动系统如何执行这些分析可能对运动路径内外的其他感知功能具有普遍适用性。例如，了解运动信号如何在眼球运动的情况下被感知为空间恒定，这是确定前进方向的重要先决条件，可能会导致对空间感知恒定性的普遍理解。同样，了解如何从背侧视觉通路中的运动线索处理三维形式可以为如何从腹侧视觉通路中的其他视觉线索衍生形式提供重要建议。
Two of the most important perceptual functions of the visual motion system are to compute our direction of heading as we move through the environment, and to deduce the three-dimensional structure of objects and the environment from motion cues. Below, we review experiments that provide insights into how these perceptual phenomena are constructed by the brain. Understanding how the motion system performs these analyses will likely have general applicability to other perceptual functions, both within and outside the motion pathway. For instance, understanding how motion signals are perceived as spatially constant despite eye movements, an important prerequisite for determining heading direction, may lead to a general understanding of spatial-perceptual constancy. Likewise, understanding how three-dimensional form is processed from motion cues in the dorsal visual pathway may provide important suggestions as to how form is derived from other visual cues in the ventral visual pathway.
