通过直流眼图 (EOG) 记录 20 名年轻健康志愿者由连续正弦旋转（0.1 Hz，+/- 90 度）引起的水平前庭眼反应 (VOR)。通过脑电图和反应时间测量来评估觉醒。虽然警觉的受试者表现出特征性 VOR 并伴有前庭眼球震颤，但快速重新定位轻弹在浅睡眠期间消失，并在很大程度上转变为补偿性平滑眼球偏差。这种觉醒减少的状态还以脑电图衰减和反应时间缓慢为特征。此外，我们观察到前庭反应完全消失但脑电图没有明显变化的短暂状态。结果表明 VOR 随唤醒变化而变化很大。产生眼球震颤快相的网状结构中的多突触系统比慢速眼球震颤成分的三神经元反射弧更容易改变。
Horizontal vestibulo-ocular response (VOR) evoked by continuous sinusoidal rotation (0.1 Hz, +/- 90 degrees) was recorded in 20 young and healthy volunteers by DC oculography (EOG). Arousal was assessed by EEG and by reaction time measurement. While alert subject showed the characteristic VOR with vestibular nystagmus, the quick repositioning flicks disappeared during light sleep and changed to largely compensatory smooth eye deviations. This state of reduced arousal was also characterized by EEG attenuation and slow reaction times. Furthermore, we observed brief states with complete extinction of the vestibular response but without significant EEG change. The results demonstrate the high variability of VOR with shifting arousal. The polysynaptic system in the reticular formation which generates the fast phase of the nystagmus beat is far more modifiable than the three-neuronal reflex arc of the slow nystagmus component.
