In the cat cerebellar flocculus without cerebrum but with intact accessory optic tract, complex spike (CS) responses to horizontal optokinetic stimuli (velocity-step at 2 degrees/s) were investigated. The directionally selective CS responses were present only during the short-duration stimuli but not during the continuous unidirectional stimuli. Following the end of the stimuli during the stationary surround phase, the CS activity was modulated in a manner opposite to the preceding CS response during the stimulation. These CS responses cannot simply be interpreted as sensory responses to the retinal slip input; they may in fact be deeply associated with the motor control command of the eye movement which would be elicited by the retinal slip.
在没有大脑但辅助视束完整的猫小脑绒球中，研究了对水平视动刺激（2度/秒的速度阶跃）的复合锋电位（CS）反应。定向选择性CS反应仅在短持续时间刺激期间出现，而在连续单向刺激期间不出现。在静止背景期刺激结束后，CS活动以与刺激期间先前CS反应相反的方式受到调制。这些CS反应不能简单地解释为对视网膜滑动输入的感觉反应；它们实际上可能与视网膜滑动引发的眼球运动的运动控制指令密切相关。
