[THE STRUCTURAL ASPECTS OF THE PARTICIPATION OF THE BRAINSTEM NUCLEI IN THE PROCESSING OF THE FUNCTIONALY DIFFERENT INFORMATIONAL FLOWS GOING THROUGH THE BASAL GANGLIA].

The structural foundation of processing of the information in the basal ganglia morphofunctional system was examined on the basis of the analysis of the investigated by the method of retrograde axonal transport projections between the functionally different parts of brain steam and basal ganglia' functionally various segments. The elements of the topic, showing to opportunity of segregated carrying of the information between the limbic and motor segments of the brain steam and the basal ganglia' similar regions were revealed in the organization of the projections between the named structures in dog. But, in the considered projection systems prevail the convergent carrying of the information testified about the possibility of the integration different modal information not only in the basic, but and in the all nuclei of the basal ganglia' morpho-functional system. The labeled «reticular» neurons with sparsely branching dendrites and long axons, which are projected to the basal ganglia, also testify about the integrative function of the investigated nucleus. The opportunity of the utilization of the received dates for making of the new models, which allow to understand better the mechanism of basal ganglia functioning in norm and pathology are discussed.
