[Cytochemical characteristics of protein content in neurons from functionally different regions of the cerebral cortex in rabbits].

Interpherometric determination of proteins in neurones of the III, IV and V layers of the visual and parietal areas and of III and V layers of the motor area of the rabbit cerebral cortex has shown that functionally different neurones have their own morpho-chemical characteristics as well. Differences are revealed between neurones of individual layers within each of the studied areas, between neurones of individual layers of the projection (motor, visual) and the so-called associative (parietal) areas as well as between neurones within each layer. The latter is apparently determined, above all, by their belonging to mono- or polymodal neurones.
