[The striopallidal projections of the zona incerta in the dog diencephalon].
The projections of individual sectors of the zona incerta (ZI) in dog diencephalon to the functionally different striatal segments were studied by the method of the antero- and retrograde axonal transport of horseradish peroxidase. The data on the interconnections of ZI with all striopallidal structures, obtained by the author before and in the present work were summarized. Among all the striatal nuclei, the the rostral, ventral and caudal ZI sectors contained the neurons that projected their fibers only to the dorsal segments of the putamen. Not a single striatal structure was found to form projections to ZI. ZI and the dorsal pallidal nuclei (globus pallidus, nucleus entopeduncularis) are reciprocally connected with almost all ZI sectors. The connections of the ventral pallidum with the ZI were not detected.
