Abstract

Abstract The spiny stellate neurons have been studied by the Golgi method in the auditory koniocortex and parakoniocortex of man. Spiny stellate cells are a consistent though not very common component of layer IV. They are not confined to specific sublayers but occur at all depths of layer IV, and also in layer IIIc. Spiny stellate cells in the auditory areas show a great variety of their dendritic arborization pattern. The presence of all intermediate forms between small pyramidal cells—which constitute the dominant cell type in layer IV and which display an extraordinary heteromorphism—and spiny stellate cells shows the close kinship between both neuronal types. The morphology and distribution of spines along the dendrites of spiny stellate neurons are similar to those of the small pyramidal cells of the same layer. The axons, which were impregnated only in their proximal portions, mostly descend, giving rise to recurrent ascending collaterals, but initially ascending axons do also occur. Spiny stellate neurons are present in the different cytoarchitectonic areas examined, and thus they are not confined to the auditory koniocortex.
