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

Retrograde axonal transport of markers was used to study the afferent projections arising from functionally diverse cortical and subcortical structures and running to various segments of the caudate nucleus, nucleus accumbens, and putamen of the dog brain. The characteristics of the spatial organization of these projections were used to analyze the morphological aspects of the segregated and convergent conduction and processing of information in the striatum which underlie striatal function.
