研究了纹状体皮质或上级丘病变对视觉检测和扫视眼球运动的影响。单侧部分切除皮层后，猴子不能发现暗点或扫视。猴子恢复了，然后没有增加双重扫视的数量，但在目标周围的初始扫视的分散略有增加。部分丘病变后，没有检测缺陷，也没有总扫视错误。有一个小的校正扫视频率增加，并没有增加在SD的初始扫视。皮质和丘关节病变后，猴在与关节病变相关的视野中似乎失明。未观察到恢复。皮质或丘显然足以进行视觉检测和扫视。这些结构之一是必要的，但关节病变产生永久性缺陷。因此，这些结构是互补的而不是冗余的，并且一致地起作用以准确地引导扫视。
The effect of lesions in striate cortex or superior colliculus on visual detection and saccadic eye movements were studied. After unilateral partial ablation of cortex, monkeys could not detect spots in the scotoma or saccade to them. The monkeys recovered and then there was no increased number of double saccades, but a slight increase in scatter of the initial saccades around the target. Following partial collicular lesions there was no detection deficit and no gross saccadic error. There was an increased frequency of small corrective saccades and no increase in the SD of the initial saccade. Following joint lesions of cortex and colliculus, the monkey appeared to be blind in the visual field related to the joint lesion. No recovery was observed. Either cortex or colliculus is apparently sufficient for visual detection and saccades. One of these structures is necessary, but joint lesions produced permanent deficits. These structures are thus complementary and not redundant and act in concert to accurately guide saccades.
