[Cholinergic neurons of the human motor cortex].
Cytoarchitectonic area 4 of human cerebral cortex was studied by histochemical demonstration of choline acetyltransferase (CAT). In layer I CAT reaction demonstrated the presence of tangential nerve fibers and synaptic endings on Cajal-Retzius neuron. High activity of the enzyme was detected in non-pyramidal cell with the axon forming the arcades and establishing contacts on bodies and apical dendrites of the layer III pyramidal neurons. Pyramidal neurons were divided into cholinergic-non-cholinoceptive, cholinergic-cholinoceptive and non-cholinergic-cholinoceptive types.
