Eye movements of monkeys were recorded while they performed a visual discrimination task before and after superior colliculus (SC) lesions or control surgery. The monkeys with SC lesions were impaired in orienting their eyes toward the visual stimuli when they were presented eccentrically 15 degrees to 32 degrees from the center of the display screen, toward which their heads were directed. This impairment in shifting the gaze to eccentric stimuli may account for the concomitant deficit in discriminating between these eccentric stimuli. The eye movement deficit appears to depend on destruction of the deep as well as more superficial layers of the SC and may reflect a disturbance in visual-oculomotor coordination.
在猴子进行上丘（SC）损伤或对照手术前后的视觉辨别任务时，记录它们的眼球运动。患有SC损伤的猴子在将眼睛朝向偏离显示屏中心15度至32度的偏心视觉刺激定向时受损，而它们的头部是朝向显示屏中心的。将目光转移到偏心刺激上的这种损伤可能解释了在区分这些偏心刺激时伴随出现的缺陷。眼球运动缺陷似乎取决于SC深层以及较浅层的破坏，并且可能反映了视觉-动眼协调的紊乱。
