[The organization of the efferent projections of the pedunculo-pontine tegmental nucleus to the dog pallidum ].
The study of pedunculo-pontine-pallidum projections in the dog's brain, which was performed using the method of retrograde axonal transport, has demonstrated the projections of a compact part (PPNc) and the lateral area of a diffuse part (PPNd) of midbrain pedunculo-pontine tegmental nucleus (PPN) to the globus pallidus, nucleus entopeduncularis and the ventral pallidum. PPNd medial area adjacent to decussation of the superior cerebellar peduncules, which is distinguished in other animals as the mesencephalic extrapiramydal area (MEA), projects only to the globus pallidus. In the dog, this tegmental area is not the major source of projections to striopallidum, therefore it appears not to be valid to distinguish it as an individual structure, it is reasonable to indicate only a topical organization PPNd projections to the pallidum. It was detected that the structures of pallidum received the projections from both cholinergic and non cholinergic initial PPN neurons.
