		These lesions were seen as foci of bilateral and symmetrical degeneration in the basal nuclei (caudate nucleus, putamen, and claustrum), midbrain, pons and medulla, in addition to multifocal lesions at the base of sulci in the cerebral cortex and in the gray matter of cerebellar folia in the ventral vermis.
		Bilateral and symmetrical foci of malacia were seen grossly in the nuclei of the cerebellum and brainstem (caudal colliculi, lateral vestibular nuclei, lateral cuneate nuclei, and lateral reticular nuclei) and the gray matter of the spinal cord associated with cervical and lumbosacral intumescences.
		Microscopic lesions occurred in internal and external capsules, caudate nucleus and claustrum (sometimes with microscopic cavities in these basal ganglia), optic nerve, and less frequently, the spinal cord where lesions were mainly confined to the ventral horns and adjacent white matter in thoracic cord segments.

		McFarland, J. and Fuchs, A. (1992) Discharge patterns in nucleus prepositus hyposglossi and adjacent medial vestibular nucleus during horizontal eye movement in behaving macaques.
		The GABAergic input to the dorsal cap and the ventrolateral outgrowth is from the nucleus prepositus hypoglossi (De Zeeuw et al., 1993), the ventral dentate nucleus and the dorsal group y (De Zeeuw et al., 1994a).
		He proposed that the inferior olive was a "comparator" of command signals from higher centers with the activities these signals evoked at lower levels in the spinal cord, which were also influenced from the periphery (Oscarsson, 1980).

		Caudal (inferior) vestibular nucleus and vestibulospinal tract 5.
		The inferior olivary nucleus is a crenated, thin gray lamina with a well defined hilus through which a multitude of olivocerebellar tract fibers issue, traversing the medial lemnisci and the olivary nucleus of the opposite side to enter the contralateral inferior cerebellar peduncle.
		The spinal nucleus of the trigeminal nerve, with its tract placed lateral to it, is classified as a general somatic afferent nucleus.

		Cells of the medial vestibular nucleus which respond to stimulation of the posterior canal project to the contralateral superior oblique and inferior rectus subdivisions of the oculomotor complex in both the rabbit and the cat (124).
		This pattern of projections is consistent with the disynaptic EPSPs (IPSPs) that have been recorded from abducens motoneurons in response to stimulation of the contralateral (ipsilateral) vestibular nerve and the monosynaptic EPSPs (IPSPs) recorded from the same cells in response to the electrical stimulation of the contralateral (ipsilateral) medial vestibular nucleus (127).
		Field potentials recorded in the abducens nucleus and triggered by spikes of position-velocity cells of the ipsilateral (contralateral) NPH nucleus are consistent with a small distal excitatory (inhibitory) connection (120).

		Axons from the large fusiform cells of the dorsal nucleus pass partly by way of the striæ medullares to the trapezoid body and lateral lemniscus and the nuclei associated with the former, and partly transversely beneath the inferior peduncle and spinal tract of the trigeminal to the trapezoid body.
		The axons arise from the nucleus of the oculomotor nerve and pass in bundles through the posterior longitudinal bundle, the tegmentum, the red nucleus and the medial margin of the substantia nigra in a series of curves and finally emerge from the oculomotor sulcus on the medial side of the cerebral peduncle.

		Additional studies target the function of the cochlear nucleus commissural projection (Shore et al, 1992; 2003), and descending projections from the superior olivary complex and inferior colliculus (Shore et al, 1991, 1992; Shore and Moore, 1998).
		Other sources include the cerebral cortex, cuneate nucleus, dorsal column nuclei, interpolar and caudal spinal trigeminal nuclei (Shore et al, 1998; 2000) and vestibular nuclei.
		The influence of the trigeminal ganglion on cochlear nucleus neurons could greatly impact processing in higher auditory centers because a high percentage of information (acoustic and somatosensory) arriving at the CN is conveyed to higher auditory centers.
