[The organization of the efferent projections of the pedunculopontine tegmental nucleus to the striatum of the dog brain].
Using the method of retrograde axonal transport, the detailed study was performed to demonstrate the efferent projections of the individual substructures of the pedunculopontine tegmental midbrain nucleus to the functionally different segments of the striatal structures in the dog. The compact and diffuse parts of this nucleus were found to project to the segments of the putamen, caudate nucleus and nucleus accumbens which belong to both limbic and motor systems. The medial region of the diffuse part adjacent to the decussation of superior cerebellar peduncles (presumably midbrain extrapyramidal area), projected only to the dorsal segments of the caudate nucleus and the putamen belonging to motor system.
