在人物画过程中，创造了一种运动错觉，将人类受试者对手臂运动的感知与他们的实际运动分开。从猴子执行相同任务时记录的皮层活动中构建的轨迹显示，实际的运动在初级运动皮层中表现出来，而可视化的（可能是感知到的）轨迹则在腹侧前运动皮层中发现。感知和动作表征可以在大脑中被区别地识别，并且可以包含在单独的结构中。
A motor illusion was created to separate human subjects' perception of arm movement from their actual movement during figure drawing. Trajectories constructed from cortical activity recorded in monkeys performing the same task showed that the actual movement was represented in the primary motor cortex, whereas the visualized, presumably perceived, trajectories were found in the ventral premotor cortex. Perception and action representations can be differentially recognized in the brain and may be contained in separate structures.
