Analysis of the morphological substrate for information processing in the pallidal nuclear complex of the dog brain in terms of the organizational characteristics of its afferent projections.
Axonal transport of retrograde markers was used to study the distribution of the afferent projections of the nuclei of the pallidal complex (the globus pallidus, the entopeduncular nucleus, and the ventral pallidum) from functionally diverse cortical and subcortical structures (cortical fields, substantia nigra, ventral tegmental field, and thalamus) in the dog brain. The results were used to analyze the morphological aspects both of the functional heterogeneity of the pallidum and integrative information processing, which underlie the mechanisms of adaptive behavior.
