The involvement of the cerebellar vermis in the acoustic reflex was analyzed in 12 cats, decerebrated or in pentobarbital anesthesia. Anatomical data suggested the existence of a connection of lobules VIII with the ventral cochlear nucleus. Single cell recording and evoked potential techniques demonstrated the existence of the acoustic projection to lobulus VIII. Electrical stimulation of this area changed the tension of the middle ear muscle and caused evoked potential responses in the caudal part of the ventral cochlear nucleus. Electrical stimulation of the motor nucleus of the facial nerve evoked a slow wave in the recording taken from the surrounding of the cochlear round window. A hypothesis is proposed which postulates the involvement of the acoustic reflex in space localization of acoustic stimuli and the action of cerebellar vermis in order to assure the stability and plasticity of the acoustic reflex arc.
对12只处于去大脑状态或戊巴比妥麻醉状态的猫，分析了小脑蚓部在听觉反射中的作用。解剖学数据表明小叶VIII与蜗腹侧核存在联系。单细胞记录和诱发电位技术证实存在向小叶VIII的听觉投射。对该区域进行电刺激可改变中耳肌肉的张力，并在蜗腹侧核尾部引起诱发电位反应。对面神经运动核进行电刺激，可在耳蜗圆窗周围记录到慢波。提出了一种假说，该假说假定听觉反射参与听觉刺激的空间定位，且小脑蚓部发挥作用以确保听觉反射弧的稳定性和可塑性。
