		The fibers of the abducent nerve pass forward through the entire thickness of the pons on the medial side of the superior olivary nucleus, and between the lateral fasciculi of the cerebrospinal fibers, and emerge in the furrow between the lower border of the pons and the pyramid of the medulla oblongata.
		The nucleus of the cochlear nerve consists of: (a) the lateral cochlear nucleus, corresponding to the tuberculum acusticum on the dorso-lateral surface of the inferior peduncle; and (b) the ventral or accessory cochlear nucleus, placed between the two divisions of the nerve, on the ventral aspect of the inferior peduncle.
		The nucleus fastigii is somewhat larger than the other two, and is situated close to the middle line at the anterior end of the superior vermis, and immediately over the roof of the fourth ventricle, from which it is separated by a thin layer of white substance.

	Solitary nucleus - Wikipedia, the free encyclopedia
		The solitary nucleus and tract are structures in the brainstem that carry and receive visceral sensation and taste from the facial (VII), glossopharyngeal (IX), vagus (X) cranial nerves, as well as the cranial part of the accessory nerve (XI).
		The nucleus is located along the length of the medulla (with a small portion in the lower pons).
		From the solitary nucleus, most information goes to the hypothalamus and cingulate gyrus, as well as to other nuclei in the brainstem (such as visceral motor or respiratory centres).

		Mossy fiber projections from the cuneate nucleus to the cochlear nucleus in the rat.
		A reciprocal connection is known to exist between the cuneate nucleus, which is a first-order somatosensory nucleus, and the cochlear nucleus, which is a first-order auditory nucleus.
		In the present study, we determined that the axonal projections from the cuneate region gave rise to mossy fiber terminals in the granule cell regions of the ipsilateral cochlear nucleus.

		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.
		The project is expedited by the use of multi-channel recording and drug-delivery probes developed by the center for neural communications, enabling us to study the physiological responses of multiple CN neurons simultaneously while delivering drugs or stimulating the trigeminal ganglion.
		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).

		Electrolytic lesion of the pyramidal tract abolished the cortically induced effects on the contralateral cuneate nucleus, as well as on the ipsilateral medial lemniscus.
		The results demonstrate that the sensorimotor cortex imposes its rhythmic patterns on the cuneate nucleus through the pyramidal tract, and that the corticocuneate network can generate normal and abnormal patterns of synchronized activity, such as delta waves, spindles and spike-and-wave complexes.
		The cuneate neurons, however, are able to generate oscillatory activity above 1 Hz in the absence of cortical input, which implies that the cerebral cortex probably imposes its rhythmicity on the cuneate by matching the intrinsic preferred oscillatory frequency of cuneate neurons.

		This nucleus, which is somewhat difficult to see, lies dorsal to the spinal tract and nucleus V and lateral to the most rostral pole of nucleus cuneatus.

		Transmission characteristics were analyzed for 21 HFA fiber-cuneate neuron pairs in which activity in the single HFA fiber of each pair reliably evoked spike output from the target neuron at a fixed latency.
		As the cuneate responses to each HFA impulse often consisted of 2 or 3 spikes, in particular at HFA input rates up to ~20 impulses s-1, the synaptic linkage displayed potent amplification and high-gain transmission, characteristics that were confirmed quantitatively in measures of transmission security and cuneate spike output measures.
		Although single HFA fibers are also known to have secure synaptic linkages with spinocervical tract neurons it is probable that this linkage lacks the capacity of the HFA-cuneate synapse for conveying precise temporal information, in an impulse pattern code, about the frequency parameter of vibrotactile stimuli.
