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 nucleus (dorsal) unipolar brush cell nifext_135 Glutamate DCN glutamatergic cell
Dorsal cochlear nucleus glutamatergic cell
Unipolar brush cells are characterized by having one dendrite that terminates in a paintbrush-like structure of dendrioles that receives input from a single mossy fiber terminal. The axon usually emanates from the opposite pole, branches 1-3 times and ends in mossy terminals. They were defined by E. Mugnaini and his colleagues in the 1990s. Dorsal cochlear nucleus
Cochlear nucleus (dorsal) vertical cell nifext_73 Glycine tuberculoventral cell
vertical cell
corn cell
Intrinsic neuron found in the deep layer of the dorsal cochlear nucleus, whose cell bodies and dendrites are intermingled among the basal dendritic trees of pyramidal cells. Their dendrites are smooth and lie in the plane of an isofrequency sheet; in sections in standard planes, parts of the dendrites are cut so they appear to be oriented vertically, perpendicular to the plane of the layers. They are inhibitory and use glycine as a neurotransmitter. Dorsal cochlear nucleus deep layer
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

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) 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 nucleus (ventral) spherical 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
