[Analysis of the morphological substrate of information processing in the striatum based on organizational characteristics of its afferent projections].

By the method of axonal transport of the retrograde markers, the afferent projections, coming from functionally different cortical and subcortical structures to various segments of the caudate nucleus, were investigated in the putamen and the nucleus accumbens of the dog brain. On the basis of the determined peculiarities of the spatail organization of these projections, the morphological aspects of the segregated and convergent conducting and processing of the information in the striatum, which underlie their functioning, were analyzed.
