Visual evoked potentials (VEPs) from eight subjects are presented from scalp sites O1, O2, T5, T6, P3 and P4. A spoked wheel was illuminated by a constantly flashing strobe. By adjusting the real angular speed of the wheel the subjective impression was given of; a stationary wheel, a wheel spinning slowly or spinning rapidly clockwise. Two visually identified components, a negativity and a positivity, were found to be of larger amplitude in response to motion. The results were interpreted as consistent with a model of AM proposing motion information to be processed within the visual system.
展示了八名受试者在头皮部位O1、O2、T5、T6、P3和P4记录的视觉诱发电位（VEP）。一个辐条轮由持续闪烁的频闪灯照亮。通过调整轮子的实际角速度，受试者会产生不同的主观感受：静止的轮子、缓慢顺时针旋转的轮子或快速顺时针旋转的轮子。发现两个视觉识别成分，一个负波和一个正波，在对运动的反应中幅度更大。结果被解释为与提出在视觉系统内处理运动信息的AM模型一致。
