[Electron microscopic and histochemical study of the localization of adenylate cylase and acetylcholinesterase in the synapses of the rat cerebral cortex and basal ganglia].

Synapses of the brain cortex and basal ganglia of the rat were studied by means of electron histochemical reactions to adenylate cyclase and acetylcholinesterase. Three types of synapses, viz. cholinergic, adrenergic and mixed, were identified. Typification was carried out on the basis of presynaptic terminal vesicle characteristics and localization of the mentioned enzymes of the synapse receptor area.
