Cochlear nucleus (dorsal) giant cell

Name: Cochlear nucleus (dorsal) giant cell
Description: Large multipolar cells located in the deep layer of the dorsal cochlear nucleus. Like the pyramidal (fusiform) cells, a principal neuron of the DCN. Their dendrites, branching sparsely across isofrequency bands, are smooth until they reach the molecular layer, where the tips are spiny. The axons join pyramidal cell axons to form the DAS (dorsal acoustic stria) through which they project to the contralateral inferior colliculus.[1]
Synonym(s): None
Abbreviation: GC
Has role: Principal neuron role[2]

Soma Specific Properties

Cell Soma Shape: Multipolar
Cell Soma Size: Large soma[3]
Soma Location: deep layer of the dorsal cochlear nucleus[3]

Dendrite Specific Properties

Dendrite location: Dendrites spread from the cell body in all directions. Dendrites are smooth where they lie in the deep layer but where the dendrites cross the pyramidal (fusiform) cell layer into the molecular layer, they become spiny. Functionally it has been demonstrated that they receive not only acoustic input in the deep layer but also proprioceptive input through the molecular layer.[4]
Spine density on dendrites: spiny low density[5]
Branching type: multipolar[3]

Axon Specific Properties

Axon myelination: myelinated
Axon projection laterality: contralateral
Origin of axon: soma and sometimes dendrite
Location of distant axon arborization: Inferior colliculus[6]
Location of local axon arborization: no local arborization[6]

Intrinsic Properties

Neurotransmitter released: likely glutamate
Neurotransmitter receptors: Glycine-gated chloride channel[5]
