VESTIBULAR NUCLEI OF HEMILABYRINTHECTOMIZED GUINEA-PIGS DURING DECOMPENSATION

Abstract

The effects of the post-brachial section of the spinal cord on the field potentials recorded from the vestibular nuclei during stimulation of the right vestibular receptors were studied in left hemilabyrinthectomized and then compensated guinea pigs. Facilitation of the field potentials in the right vestibular nuclear complex and inhibition in the left nuclei was observed. This confirmed that the spinal cord was involved in the compensation of the release syndrome brought about by the lesion of 1 labyrinth. The possible mechanisms underlying such a compensation are discussed.
