前庭眼反射(VOR)的唯一功能是在头部运动期间使眼球向与头部运动相反方向做等量运动,进而稳固视觉图像于视网膜上,确保最大的视觉精确度,其基本反射弧是:前庭感受器-前庭核二级神经元-动眼神经元-眼球。增益和位相是定量分析VOR的重要指标,眼震慢相速度与头运动速度之比值即为增益。因此,理想的增益正常值应等于1。
The only function of vestibular reflex (VOR) is to move the eyeball in the opposite direction of the head movement during the head movement, thus stabilizing the visual image on the retina to ensure maximum visual accuracy. The basic reflex arc is: Vestibular receptors - vestibular nuclei secondary neurons - oculomotor neurons - the eyeball. The gain and phase are important indicators for quantitative analysis of VOR. The ratio of nystagmus slow motion to head velocity is the gain. Therefore, the ideal normal gain should be equal to one.
