[Structure of the terminal portions of the monoaminergic afferent system in the parietal area of the rat cerebral cortex].
Construction and layer-by-layer distribution of catecholaminergic structures in the rat cortical parietal area have been studied electron microscopically. The method of 6-hydroxydopamine (6-OH-DA)-induced chemical rearrangements in the monoaminergic cerebral systems has been used. The intracisternal administration of 6-OH-DA (300 mcg) produces certain structural rearrangements in axons, their terminals and dendrites situating mainly in layers I, II, V and VI; within their limits the structural rearrangements are distributed unevenly. The catecholaminergic structures organization revealed is considered as a morphological base of varied functions of these systems.
