[Corticofugal effects on the neuronal activity of the vestibular nuclei in the cat].
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.
