[Neuronal composition and interneuronal connections of field 5 of the parietal association cortex of cats].
Field 5 of the cat neocortex was studied by the Golgi method. Characteristic features here are as follows: predominance of pyramidal cells in layers II-III and existence of large forms (40X26 micron) among them; single and clustered giant pyramidal neurons (70X23 micron) in layer V; large (25-30 micron in diameter) and giant (40-45 micron in diameter) stellate cells with radial dendrites, single or gathered in groups, in layers V--VI; few efferent spindle-like neurons (40X20 micron) in layers V-VI. Stellate cells found in layers II-VI probably unite the pyramidal cells localized within one or several layers. Some of the stellate cells in layers II-III establish long horizontal connections within the field. Interneuronal connections are formed by axo-somatic and axo-dendritic terminals with the prevalence of the latter; dendro-dendritic and axo-axonic contacts were rarely observed.
