title: Vestibular nuclei of hemilabyrinthectomized guinea pigs during decompensation.
abstract: 1. 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 have been studied in left hemilabyrinthectomized and then compensated guinea pigs. 2. Facilitation of the field potentials in the right vestibular nuclear complex and inhibition in the left nuclei have been observed. 3. These results confirm that the spinal cord is involved in the compensation of the release syndrome brought about by the lesion of one labyrinth. 4. The possible mechanisms underlying such a compensation are discussed.
