[The connections of the zona incerta of the dog diencephalon with the substantia nigra, the ventral tegmental area and the pedunculopontine tegmental nucleus].
This study used the technique based on horse-radish peroxidase retrograde and anterograde transport to examine the organization of the connections of different sectors of the zona incerta (ZI) of the diencephalon with the substructures of the substantia nigra, the ventral tegmental area and the pedunculopontine tegmental nucleus of dog mesencephalon. It was found that these structures were interconnected with each other. In the organization of the projections studied, the elements were detected that suggested the possibility of the segregated conduction of the functionally various information via the established pathways. Alongside with this, the convergence of the projection fibres of the neurons of the mesencephalic nuclei substructures to ZI, described in all its sectors, together with the projections of all the ZI sectors to these neurons, indicates the possibility of the integration of functionally various information both at ZI level and at the level of mesencephalic structures studied in this work.
