运动信息对于确定人类和非人类灵长类动物的三维 (3-D) 环境结构非常重要1-8。例如，如果一个人闭上一只眼睛并观看一个均匀照明、形状不规则的物体，他不太可能正确猜测其形状。但如果物体移动，正确的形状就会立即显现出来9。尽管已经提出了各种理论7,8,10-15，但人们对灵长类动物视觉系统实际上是如何做到这一点知之甚少。我们开发了新颖的、高度受控的运动刺激，与心理物理和生理技术结合使用，研究如何从运动中获得 3D 结构。我们证明恒河猴可以像人类受试者一样从运动中检测 3D 结构。此外，这两个物种对显示的某些参数的依赖性表明，为了实现这种更高的视觉功能，信息在空间和时间上都是集成的。
Information on motion is important for the determination of the three-dimensional (3-D) structure of the environment for both human and non-human primates1–8. For example, if a person were to close one eye and look at an evenly illuminated, irregularly shaped object, he would be unlikely to guess its shape correctly. But if the object is moved about, the correct shape immediately becomes apparent9. Little is known about how the primate visual system actually does this, although various theories have been proposed7,8,10–15. We have developed novel, highly controlled motion stimuli to use with psychophysical and physiological techniques to study how 3-D structure is obtained from motion. We show that the Rhesus monkey can detect 3-D structure from motion in the same way as human subjects. Furthermore, the dependence of both species on certain parameters of the display shows that information is integrated both spatially and temporally for this higher visual function.
