The vestibuh^r nuclei comprise the triangular nucleus of Schwalbe (NSc) which occupies a position in the central gray matter in the dorsal held immediately below the floor of the fourth ventricle; and a nucleus consisting of large cells dispersed among which are many bundles of axons, Deiters' nucleus (ND). Both of these vestibular nuclei receive fibers from the vestibular portion of the ear, and although the exact function of each nucleus is not adequately understood, pathological.
