Abstract

The pigeon cochlear nucleus angularis (NA) and nucleus magnocellularis (NM) were analyzed with Golgi and Nissl techniques, NA was divided into a medial NAm and NA proper, which could be subdivided further into an intermediate NAi and lateral NAI. NAm contained a mostly homogeneous population of a unique multipolar cell type with very short dendrites and large somatic spines, NA proper contained four cell types: large, medium, and small multipolars, and medium bipolar, The medium multipolar cells were most common, and resembled the multipolar cells of the mammalian ventral cochlear nucleus, NMpresented a homogenous appearance with a mediolateral gradient of cell size and shape, Medially located higher best frequency NM principal cells had round cell bodies with small somatic spines and few dendrites, By comparison, laterally located low best frequency NM stellate cells had more dendrites and spindle shaped cell bodies, The similarities between the cell types of NA and the cell types in the cochlear nuclei of other amniote vertebratesmay be due to homology or convergent evolution, Copyright (C) 2000 S.
