The neuronal architecture of the cochlear nucleus of the cat

TLDR

The study produced a detailed cytoarchitectonic atlas of the cat cochlear nucleus by combining Nissl, Protargol, and rapid Golgi staining, characterizing neuronal types, mapping them by serial sections, and plotting their positions in the atlas. This integrated Golgi‑Nissl approach allows precise localization of functionally defined neuronal types within the cochlear nucleus.

Abstract

Abstract A detailed parcellation of the entire cochlear nucleus of the cat was prepared with the Nissl and Protargol methods in the form of a cytoarchitectonic atlas. Neuronal cell types were characterized in rapid Golgi impregnations. Golgi impregnations were used to define the specific features of the mature neuronal types. Neurons from the Golgi preparations were systematically mapped according to type and location in serial sections. These neurons were then plotted in corresponding positions in the cytoarchitectonic atlas. This combined Golgi‐Nissl approach provides a scheme in which neuronal types, defined in terms of a number of functionally significant features, can be precisely localized within the cochlear nucleus.
