反复作旋转或冷热水试验可使动物眼震反应减弱,这称之为前庭习服。许多实验证明小脑蚓部尤其是前庭小脑区对前庭习服发生和维持起重要作用。作者研究了促甲状腺释放激素(TRH)对豚鼠前庭习服的影响。用健康成年豚鼠5只为实验组,另5只为对照组。用一直径40cm的转盘。其上有三只固定豚鼠的盒子,以0.5°/秒~2的匀加速度作逆时针旋转,当角速度到60°/秒时保持匀速旋转60秒,突然停止,2分钟后再重复上述实验,这样仅右水平半规管受刺激。本实验是在完全黑暗的环境中进行,每天作30次,连续15天,用眼震电图记录实验结果,以眼震持续时间和次数为参数。实
Repeatedly rotating or hot and cold water test animal Nystagmus weakened, which is called vestibular uniform. Many experiments show that cerebellar vermis, especially the vestibular cerebellar region, plays an important role in the occurrence and maintenance of vestibular clothing. The authors investigated the effects of thyrotropin releasing hormone (TRH) on vestibular clothing in guinea pigs. Five healthy adult guinea pigs were used as experimental group and the other five as control group. Use a 40cm diameter turntable. There are three fixed guinea pigs on the box, with a uniform acceleration of 0.5 ° / s ~ 2 counterclockwise rotation, when the angular velocity to 60 ° / s to maintain constant rotation 60 seconds, suddenly stopped, 2 minutes and then repeat the above experiment, so Only the right horizontal semicircular canal is stimulated. The experiment is carried out in a completely dark environment, 30 times a day for 15 consecutive days, the experimental results recorded by nystagmus, the nystagmus duration and the number of times as a parameter. real
