人类和非人类灵长类动物能够从运动显示器中感知三维结构。用三维物体运动显示来验证猴上级颞多感觉区（STPa）前区神经元对三维物体运动显示有选择性反应的假设。猴子执行的反应时间的任务，需要检测的变化，在三维透明球体显示器的结构的分数。神经元能够区分结构化和非结构化的三维光流。这些细胞可以区分刺激呈现时和动物检测显示器中结构数量时的结构与运动的变化。这些神经元中的一些也被调整为球体刺激的特征。细胞也进行了测试与导航运动和许多被发现都响应三维结构从运动和导航运动。这些结果表明，STPa神经元代表了三维表面结构的特定方面，并且STPa内的神经元有助于从运动感知三维结构。
Human and non-human primates are able to perceive three-dimensional structure from motion displays. Three-dimensional structure-from-motion (object-motion) displays were used to test the hypothesis that neurons in the anterior division of the superior temporal polysensory area (STPa) of monkeys can selectively respond to three-dimensional structure-from-motion. Monkeys performed a reaction time task that required the detection of a change in the fraction of structure in three-dimensional transparent sphere displays. Neurons were able to distinguish structured and unstructured three-dimensional optic flow. These cells could differentiate the change in structure-from-motion at stimulus presentation and when the animal was detecting the amount of structure in the display. Some of these neurons were also tuned for characteristics of the sphere stimuli. Cells were also tested with navigational motion and many were found to respond both to three-dimensional structure-from-motion and navigational motion. These results suggest that STPa neurons represent specific aspects of three-dimensional surface structure and that neurons within STPa contribute to the perception of three-dimensional structure-from-motion.
