Using the method of the retrograde axonal transport of horseradish peroxidase, it was determined that in dog, the projections from globus pallidus, nucleus entopeduncularis, substantia nigra and pedunculopontine nucleus were directed to all the regions of zona incerta. In the present study, no topical features were detected in the organization of these projections in dog, since after the injections of the marker in different regions of zona incerta, similar distribution of labeled neurons was observed in basal ganglia. The projections from the striatum to zona incerta were not found.
