Cochlear nucleus (ventral) octopus cell

Name: Cochlear nucleus (ventral) octopus cell
Description: 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.[1]
Synonym(s): Ventral cochlear nucleus octopus cell, octopus cell
Abbreviation: OC
Has role: Principal neuron role[2]
Super-category: Neuron
Id: nifext_72
PMID: PMID 5801446
Related to: Onset responses to tones[3]
Organism: Mammal

Soma Specific Properties

Cell Soma Shape: Oval[4]
Cell Soma Size: Large soma[4]
Soma Location: Cochlear nuclear complex, ventral cochlear nucleus, octopus cell area, dorsal tail of ventral cochlear nucleus, nucleus interfascicularis[1]

Dendrite Specific Properties

Spine density on dendrites: Smooth[5]

Axon Specific Properties

Axon myelination: myelinated[2]
Axon projection laterality: contralateral[2]
Origin of axon: soma and sometimes dendrite[6]
Location of distant axon arborization: Ventral nucleus of lateral lemniscus, superior paraolivary nucleus[7]
Location of local axon arborization: In some species (mice) but not in others (cats) octopus cells have local collaterals in the octopus cell area and contact granule cells in the granule cell lamina.[8]

Intrinsic Properties

Neurotransmitter released: Glutamate[8]
Neurotransmitter receptors: AMPA-type glutamate-gated cationic channel[9]
Molecular constituents: KCNA, HCN1, parvalbumin, calretinin[10]

EditorialNoteI can't track down the reference to the nu I can't track down the reference to the nucleus interfascicularis. The reference given doesn't mention the nucleus and according to Brain Info, there are two nuclei, one in the midbrain tegmentum and one associated with the hypoglossal nucleus, that go by that name. Needs clarification that go by that name. Needs clarification
