Cochlear nucleus (dorsal) pyramidal neuron

Name: Cochlear nucleus (dorsal) pyramidal neuron
Description: 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.
Synonym(s): fusiform cell, dorsal cochlear nucleus pyramidal cell
