Abstract

Neuronal responses to stimulation of vestibular (V1), motor and orbital brain cortex were recorded extracellularly in lateral and medial vestibular nuclei of bulbar complex in experiments carried on nonanesthetized immobilized cats. Both phasic and (more often) tonic responses mainly of inhibitory type were observed. In morphological experiments the horseradish peroxidase was injected into the above nuclei. Marked neurons were found in the anterior supra- and ectosylvian brain gyri, in the region of cruciform sulcus and orbital cerebral cortex. The obtained data are discussed in the aspect of corticovestibular interaction.

摘要

在对未麻醉的固定猫进行的实验中,在延髓复合体的外侧和内侧前庭核中,细胞外记录了神经元对前庭(V1)、运动和眶脑皮质刺激的反应。观察到主要为抑制型的相位和(更常见的)紧张性反应。在形态学实验中,将辣根过氧化物酶注入上述核团。在前额上回和外侧沟回、十字沟区域和眶脑皮质中发现了标记神经元。从皮质-前庭相互作用的角度对所得数据进行了讨论。
