以往的实验，以确定是否增加或减少的增益视动性眼震（OKN）的中央视网膜的闭塞涉及使用的静态边缘的闭塞和不匹配的对比度。在控制这些因素的情况下，证实了OKN增益因中央视网膜的阻塞而严重降低，但仅在刺激速度高于约30°/秒时。水平OKN的增益被发现，不增加显示器的宽度，如果横向边缘模糊。中央驱动OKN的高增益可能与高等哺乳动物在复杂视差视野中稳定给定距离处物体的图像的能力有关。
Previous experiments to decide whether the gain of optokinetic nystagmus (OKN) is increased or decreased by occlusion of the central retina involved the use of stationary edges on the occluder and unmatched contrasts. With these factors controlled, it was confirmed that OKN gain is severely reduced by occlusion of the central retina but only at stimulus velocities above about 30°/sec. The gain of horizontal OKN was found not to increase with increasing width of the display if the lateral edges are blurred. The high gain of centrally driven OKN may be related to the ability of higher mammals to stabilize the images of objects at a given distance in a complex parallactic visual field.
