Abstract: | Neuronal responses to stimulation of vestibular motor and orbital cerebral cortex were recorded by extracellular techniques in the lateral and medial vestibular nuclei of the bulbar complex during experiments on unanesthetized, immobilized cats. Both phasic and (mostly) tonic response of predominantly inhibitory type were observed. Horseradish peroxidase was injected into the aforementioned nuclei of the vestibular complex during the course of morphological experiments. Labeled neurons were found in the anterior supra- and ectosylvian cerebral gyri, the region of the cruciform sulcus, and that of the orbital cerebral cortex. Findings are discussed from the aspect of corticovestibular interaction.Ivano-Frankovsk Medical Institute, Soviet Ministry of Health.
