Some neurons in the visual cortex of awake monkeys visually tracking a moving target showed receptive fields that were excited only by stimulus motion relative to a background, while other neurons responded to any kind of stimulus motion. This result was found with two methods, one in which tracking eye movements were identical in both relative-motion and absolute-motion conditions, and another in which stimulus motions on the retina were identical in both conditions. This response pattern can differentiate translation of the retinal image during eye movement from motion of objects in the world.
在清醒猴子的视觉皮层中，一些视觉追踪移动目标的神经元显示出其感受野仅被相对于背景的刺激运动所兴奋，而其他神经元则对任何类型的刺激运动都有反应。这一结果通过两种方法得到，一种方法是在相对运动和绝对运动条件下追踪眼动相同，另一种方法是在两种条件下视网膜上的刺激运动相同。这种反应模式可以区分眼动过程中视网膜图像的平移与世界中物体的运动。
