The effects of degrading retinal image velocity information on suppression of the vestibulo-ocular reflex have been assessed through tachistoscopic presentation of target sources in man. Subjects were required to fixate a head-fixed display during exposure to a 0.5 Hz sinusoidal angular oscillation of the head at +/- 60 degrees/s. In the first experiment it was found that the degree of suppression was progressively degraded as the interval between successive target presentations was increased from 10 to 3,000 ms. In the second experiment no effect of changing the duration of the target pulse was observed over a range from 20 to 1,000 microseconds. The results appear consistent with a model of visual motion sensitivity in which relative velocity information is obtained by the temporal integration of responses from spatially separated retinal cells.
通过对人类进行速示器呈现目标源，评估了降解视网膜图像速度信息对前庭眼反射抑制的影响。要求受试者在头部以±60度/秒的频率进行0.5赫兹正弦角振荡期间，注视固定于头部的显示器。在第一个实验中发现，随着连续目标呈现之间的间隔从10毫秒增加到3000毫秒，抑制程度逐渐降低。在第二个实验中，在20到1000微秒的范围内，未观察到改变目标脉冲持续时间的影响。这些结果似乎与视觉运动敏感性模型一致，在该模型中，相对速度信息是通过对空间上分离的视网膜细胞的反应进行时间积分而获得的。
