Visual stimuli that isolate pupil color and pupil grating responses in human vision have been used to investigate the properties, of stimulus-specific pupil responses in the rhesus monkey. We measured and compared pupil responses to light flux increments, isoluminant chromatic stimuli, and gratings of equal and lower space-averaged luminance. The parameters investigated were luminance contrast and chromatic saturation. The results demonstrate clearly the existence of pupil color, pupil grating and pupil light reflex responses in the rhesus monkey. Comparison of pupil color and pupil grating responses of equivalent amplitude reveals similar onset response latencies. However, both are approximately 40 ms longer than the corresponding pupil light reflex latency. In general these pupil responses are qualitatively similar to those observed in humans. However, when compared to equivalent human data, pupil onset response latencies are some 80-100 ms shorter and the pupil shows more rapid recovery from constriction.
在人类视觉中，用于分离瞳孔颜色和瞳孔光栅反应的视觉刺激已被用于研究恒河猴中特定刺激的瞳孔反应特性。我们测量并比较了瞳孔对光通量增量、等亮度色度刺激以及等亮度和低空间平均亮度光栅的反应。所研究的参数为亮度对比度和色度饱和度。结果清楚地表明恒河猴中存在瞳孔颜色、瞳孔光栅和瞳孔光反射反应。等效幅度下瞳孔颜色和瞳孔光栅反应的比较显示出相似的起始反应潜伏期。然而，两者都比相应的瞳孔光反射潜伏期长约40毫秒。一般来说，这些瞳孔反应在质量上与在人类中观察到的相似。然而，与等效的人类数据相比，瞳孔起始反应潜伏期短约80 - 100毫秒，并且瞳孔从收缩中恢复得更快。
