Cochlear nucleus chestnut cell
| Name: | Cochlear nucleus chestnut cell |
| Description: | 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. |
