扫视系统精确地补偿了由上级丘的微刺激产生的人眼位置的扰动。这就要求有关刺激引起的眼睛位置变化的信息由视网膜外来源提供，要么是眼外肌中的本体感受末梢，要么是中枢产生的必然放电。在消除眼外肌本体感觉后，补偿仍然完整，表明必然的放电提供准确的眼睛位置信息。
The saccadic system accurately compensates for perturbations of [human] eye position produced by microstimulation of the superior colliculus. This requires that information about the stimulation-induced change in eye position be provided by an extraretinal source, either proprioceptive endings in extraocular muscles or a centrally generated corollary discharge. Compensation remains intact after elimination of extraocular muscle proprioception, demonstrating that corollary discharge provides accurate eye position information.
