Organization of projections of the zona incerta of the diencephalon to pallidal structures in the dog brain.
Detailed studies of the organization of individual sectors in the zona incerta of the diencephalon to functionally diverse pallidal structures in the dog brain were performed by antero- and retrograde axon transport of horseradish peroxidase. The results showed that neurons in the caudal sector of the zona incerta innervate the globus pallidus and entopeduncular nucleus, which receive more extensive innervation from motor structures. The same pallidal structures receive projections from occasional neurons in the dorsal and causal sectors of the zona incerta. No connections of the zona incerta with the limbic ventral pallidum were found.
