To clearly see a moving object, an observer must rotate his or her eyes with a velocity that matches that of the object. Such rotations are called smooth pursuit eye movements, and they depend critically on the ability of the primate brain to integrate information about object velocity from various local motion signals. When the local motion signals are in conflict, it is possible to use smooth pursuit eye movements as a continuous read-out of the motion integration process. This review discusses the results of recent behavioral experiments that have taken this approach, along with relevant neurophysiological and computational studies.
为了清晰地看到一个移动的物体，观察者必须以与物体速度相匹配的速度转动眼睛。这种转动被称为平稳跟踪眼球运动，它们严重依赖于灵长类动物大脑整合来自各种局部运动信号的物体速度信息的能力。当局部运动信号相互冲突时，可以将平稳跟踪眼球运动用作运动整合过程的连续读数。这篇综述讨论了采用这种方法的近期行为实验结果，以及相关的神经生理学和计算研究。
