Projections of the second cervical dorsal root ganglion to the cochlear nucleus in rats
Biotinylated dextran amine is injected into the cochlear nucleus or dorsal root ganglion at the second cervical segment and primary somatosensory projections contribute to circuits that are hypothesized to mediate integrative functions of hearing.

Projections of the lateral reticular nucleus to the cochlear nucleus in rats
The lateral reticular nucleus projections are consistent with known organizational principles of non‐auditory inputs to the GCD and formed against thin dendritic profiles characterized by plentiful microtubules and the presence of fine filopodial extensions that penetrated the ending.

Trigeminal Contributions to the Dorsal Cochlear Nucleus in Mouse
It is found that the spinal trigeminal nucleus indeed projects to DCN, targeting granule cells and unipolar brush cells, however, direct axonal projections from the trigEMinal ganglion itself were undetectable, and secondary brainstem sources carry non-auditory signals to the DCN in mice that could provide a processed trigeminals signal to theDCN, but primary trigemINAL afferents are not integrated directly by DCN.

Descending projections from the inferior colliculus to the dorsal cochlear nucleus are excitatory
These descending projections to the DCN from the IC were topographic and suggest a feedback pathway that could underlie a frequency‐specific enhancement of some acoustic signals and suppression of others, a feature of excitatory neurotransmission.

Differential projections from the cochlear nucleus to the inferior colliculus in the mouse
Electrophysiological recordings are used to establish the frequency at the site of the anterograde dye injection for the VCN and DCN of the CBA/CaH mouse to investigate the pattern of CN connections in the inferior colliculus in more detail.

Tonotopic organization of vertical cells in the dorsal cochlear nucleus of the CBA/J mouse
It is suggested that vertical cells are well positioned for providing immediate, frequency‐specific inhibition onto cells of the DCN and AVCN to facilitate spectral processing.

Microcircuits of the Ventral Cochlear Nucleus
This chapter concentrates on the connectivity and synaptic microcircuits, including the key molecular synaptic components that allow the principal cells (bushy and stellate cells) to accomplish their functions.

Projections of the pontine nuclei to the cochlear nucleus in rats
The PN represent a key station between the cerebral and cerebellar cortices, so the pontocochlear nucleus projection emerges as a significant source of highly processed information that is introduced into the early stages of the auditory pathway.

Morphological Evidence for Secondary Vestibular Afferent Connections to the Dorsal Cochlear Nucleus in the Rabbit
An analysis of central afferent projections to the dorsal cochlear nucleus (dCo), one of the three target nuclei of the auditory nerve, was made using retrograde axonal tracer, wheat germ agglutinin-horseradish peroxidase (WGA-HRP) in the rabbit, showing sparse bilateral connections from the caudal three quarters of the vestibular nuclear complex (VNC).

Projections from the ventral cochlear nucleus to the dorsal cochlear nucleus in rats
Structural differences between planar and radiate neurons suggest that they subserve separate functions in acoustic processing, and that they are sensitive to a broad range of frequencies.

Trigeminal projections to hypoglossal and facial motor nuclei in the rat
This study was undertaken to identify the trigeminal nuclear regions connected to the hypoglossal (XII) and facial (VII) motor nuclei in rats. Anterogradely transported tracers (biotinylated dextran...

Organisation of reciprocal connections between trigeminal and vestibular nuclei in the rat
Morphological analysis of vestibular neurones demonstrated that vestibulo‐trigeminal neurones are relatively small and belong to a different population than those receiving projections from the trigeminal nuclei.

Trigeminal ganglion innervates the auditory brainstem
This study provides the first evidence that the trigeminal ganglion innervates the cochlear nucleus and superior olivary complex and may be related to integration mechanisms involving the auditory end organ and its central targets.

Mossy fiber projections from the cuneate nucleus to the cochlear nucleus in the rat
It is 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, indicating that somatosensory cues are intimately involved with information processing at this early stage of the auditory system.

Topography of primary afferent projections in the trigeminal sensory nuclei of rats.
The results indicate that the projections to all the brain stem trigeminal subnuclei, including the principal sensory nucleus and the three subdivisions of the spinal trigeminals nucleus, are topographic; however, the extent to which label from different whisker rows overlap appears to differ from subdivision to subdivision.

Central distribution of trigeminal and upper cervical primary afferents in the rat studied by anterograde transport of horseradish peroxidase conjugated to wheat germ agglutinin
Comparisons of the central projection fields of trigeminal and upper cervical primary afferents indicated a somatotopic organization but with a certain degree of overlap.
