The nystagmus response to rotatory acceleration was investigated in rats. The stimulus was exerted by a turntable accelerated 13.3%/sec2 for 9 seconds and after 1-2 minutes decelerated accordingly. Eye movements were recorded using the search coil technique. The duration of postrotatory nystagmus and speed of slow component velocity gain were recorded. After unilateral neck muscle sectioning no change appeared. After bilateral sectioning the nystagmus response was increased with a remaining high gain and prolonged response duration. The experiments show the influence by the muscles on the velocity storage mechanism.
研究了大鼠对旋转加速度的眼球震颤反应。刺激由一个以13.3%/秒²加速9秒的转盘施加,1至2分钟后相应减速。使用搜索线圈技术记录眼球运动。记录了旋转后眼球震颤的持续时间和慢相速度增益的速度。单侧颈部肌肉切断后无变化。双侧切断后,眼球震颤反应增强,增益仍然较高,反应持续时间延长。实验表明了肌肉对速度存储机制的影响。
