前庭眼反射通过产生与每次旋转头部运动相等或相反的平滑眼球运动来帮助稳定视网膜图像。众所周知，只要在头部转动过程中出现持续的图像运动，反射就会经历适应性可塑性或“运动学习”：由此产生的反射变化是逐渐发生的，有助于恢复图像稳定性。一种新的方法使得根据自然前庭刺激反应的总潜伏期识别包含运动学习部位的通路成为可能。最快的通道需要14毫秒来启动前庭-眼反射，但运动学习的位置在通道中，潜伏期至少为19毫秒。
The vestibulo-ocular reflex helps to stabilize retinal images by generating smooth eye movements that are equal to and opposite each rotatory head movement. It is well known that the reflex undergoes adaptive plasticity or "motor learning" whenever there is persistent image motion during head turns: the resulting changes in the reflex occur gradually and help to restore image stability. A new approach makes it possible to identify the pathways containing the site of motor learning according to their total latency in response to natural vestibular stimuli. The fastest pathways required 14 milliseconds to initiate a vestibulo-ocular reflex, but the site of motor learning was in pathways having latencies of at least 19 milliseconds.
