在猫中测量前庭眼反射的增益（眼速度/头速度）。在0.03-1.2 Hz的频率范围内，其在黑暗中的正常值为9.9。当猫长期佩戴左右反转棱镜时，在0.05Hz下，增益在8天内下降到约0.1。这可能是一种适应性变化，因为它有助于减少头部运动期间的视网膜图像滑动。这种适应性反应被取消的前庭小脑，主要是绒球和结节。前庭小脑的功能之一显然是检测前庭眼反射中的辨距障碍，并通过自动增益控制的方法进行修复。
The gain of the vestibuloocular reflex (eye velocity/head velocity) was measured in cats. Its normal value in the dark was 9.9 over the frequency range 0.03-1.2 Hz. When cats wore left-right reversing prisms chronically, the gain decreased to about 0.1 in 8 days at 0.05 Hz. This may have been an adaptive change because it helped to reduce retinal image slip during head movement. This adaptive response was abolished by removal of the vestibulocerebellum, principally the flocculus and nodulus. One function of the vestibulocerebellum is apparently to detect dysmetria in the vestibuloocular reflex and repair it by a method of automatic gain control.
