Cochlear nuclear complex | ||
| Cochlear nucleus (dorsal) granule cell | nifext_77 | Glutamate | Small excitatory interneuron found in the dorsal and ventral cochlear nucleus that resembles the cerebellar granule cell. The dendrites are short with claw-like endings that form glomeruli to receive mossy fibers. Its axon projects to the molecular layer of the dorsal cochlear nucleus where it forms parallel fibers that cross iso-frequency bands. As in the cerebellum they are intermingled with Golgi and unipolar brush cells. | Cochlear nuclear complex | |
| Cochlear nucleus (dorsal) pyramidal neuron | nifext_74 | Excitatory neurotransmitter | fusiform cell dorsal cochlear nucleus pyramidal cell |
Bipolar neuron in dorsal cochlear nucleus, whose cell bodies form a band in the pyramidal cell layer. Characterized by a spiny apical dendritic tree in the molecular layer and a smooth basal dendritic tree in the deep layer. The apical dendrites have many branches which are contacted by parallel fibers from granule cells, whereas the basal dendrites have few branches and receive inputs from the auditory nerve. | Cochlear nuclear complex |
| Cochlear nucleus (ventral) D cell | nifext_69 | Glycine | D multipolar cell type II (Cant 1981) onset-chopper responses to tones radial stellate wide-band inhibitor |
One of two types of multipolar or stellate cells, D stellate cells are glycinergic inhibitory neurons named for having an axon that projects dorsalward into the dorsal cochlear nucleus and that exits through the intermediate acoustic stria to innervate the contralateral cochlear nucleus. Axons have widespread collaterals in the ventral cochlear nucleus and in the deep layer of the dorsal cochlear nucleus. | Ventral cochlear nucleus |
| Cochlear nucleus (ventral) bushy cell | nlx_cell_20081201 | Glutamate | Bushy neuron Bushy cell ventral cochlear nucleus bushy cell |
Bushy cells in the anteroventral cochlear nucleus have one to four primary dendrites which branch profusely, giving them a "bushy" appearance. They project to the superior olivary nuclei. They carry information that is used to localize sounds in the azimuthal plane. Three types of bushy cells differ in the shapes of their somata and in their patterns of projection. The cell somata of these neurons have been described as "spherical" in the anterior division of the AVCN and "globular" in the posterior division of the AVCN. Large spherical bushy cells project to the medial superior olivary nuclei bilaterally, globular bushy cells project to the contralateral medial nucleus of the trapezoid body. Small spherical bushy cells project to the vicinity of the ipsilateral lateral superior olivary nucleus but it is not yet clear which cells are their targets. Their inputs from the spiral (cochlear) ganglion arise via the end bulbs of Held. | Ventral cochlear nucleus |
| Cochlear nucleus (ventral) globular bushy cell | nifext_70 | Glutamate | The distinction between globular and spherical bushy cells was originally reported by Osen on the basis of a difference in the shape of the cell bodies. Globular bushy cells lie in and around the root of the auditory nerve. Their axons project to the contralateral medial nucleus of the trapezoid body (MNTB), innervating principal cells with a calyx of Held. | Ventral cochlear nucleus | |
| Cochlear nucleus (ventral) multipolar T cell | nifext_68 | Glutamate | T multipolar cell T stellate cell type I chopper planar multipolar |
Principal cells of the ventral cochlear nucleus are named for having the axon exit the cochlear nucleus through the Trapezoid body. A band of dendrites in an isofrequency lamina receives input from a small number of auditory nerve fibers. Sharp tuning is enhanced by sideband inhibition. The population of T stellate cells encodes the spectra of sounds. | Ventral cochlear nucleus |
| Cochlear nucleus (ventral) multipolar cell | nlx_cell_20081202 | Multipolar neuron located in the ventral cochlear nucleus with multiple long dendrites extending from the cell soma. Two subclasses (D and T) are recognzed based on their alignment with auditory nerve fibers. Both types have axon collaterals that terminate locally near the cell soma. | Cochlear nuclear complex | ||
| Cochlear nucleus (ventral) octopus cell | nifext_72 | Glutamate | Ventral cochlear nucleus octopus cell octopus cell |
Large neuron located in the octopus cell area of the posterior division of the ventral cochlear nucleus (called dorsal tail of the ventral cochlear nucleus by Cajal and nucleus interfascicularis by Lorente de No), whose dendrites emanate from one side of the cell body, giving them a shape reminiscent of an octopus. | Cochlear nuclear complex Ventral cochlear nucleus Octopus cell area Dorsal tail of ventral cochlear nucleus Nucleus interfascicularis |
| Cochlear nucleus chestnut cell | nlx_cell_200903010 | Chestnut neuron Chestnut cell |
Type of intrinsic neuron located in the granule cell layer of the cochlear nucleus, characterized by a small (~10 um) cell body and 1-2 stubby dendrites emerging from one side of the soma, ending in a terminal tuft. Finger-like projections emerge from both the dendritic tuft and the soma. The cell gets its name from the irregular surface of the cell soma, characterized by numerous scallops, blebs and other protrusions, giving it the appearance of a chestnut. At the ultrastructural level, the cell body and proximal dendrites are rich in Golgi apparatus, rough endoplasmic reticulum and free ribosomes with a large, centrally located pale nucleus with a smooth nuclear membrane. Although it resembles the unipolar brush cell in some respects, it is differentiated by the gradual tapering of the primary dendrites in the transition from the cell soma and the fact that every protuberance of the dendrite is "prominantly synaptic" according to Weedman et al. (1996). It is a target of mossy fiber synapses. | Cochlear nuclear complex | |
