Single unit activity was studied in the intermediate and deep layers of the superior colliculus in two trained cats. Eye movements were recorded with a magnetic search coil, the head being fixed. Discharge rates which varied as a function of eye position were consistently observed in 7 of 67 (about 10%) of the sample of eye movement-related units. These units showed similar changes in firing rate as a function of eye position in total darkness and during task related fixation of visual targets and thus appear to convey an "eye position" signal. Their activity may originate either from proprioception or from corollary discharge.
在两只经过训练的猫的上丘中间层和深层研究了单个神经元活动。用磁搜索线圈记录眼动，头部保持固定。在67个与眼动相关的神经元样本中，有7个（约10%）的放电率随眼位变化而持续变化。这些神经元在完全黑暗以及与任务相关的视觉目标注视期间，其放电率随眼位呈现出相似的变化，因此似乎传递了一个“眼位”信号。它们的活动可能源于本体感觉或伴随放电。
