[Projections of the tegmental ventral field, substantia nigra formations and amygdaloid nuclei to different segments of the caudate nucleus and nucleus accumbens in the dog].
Spatial organization of progections of amygdala, tegmentum ventral field and of substantia nigra formations on different regions of caudal nuclei and of the nucleus accumbens in dog was studied by means of retrograde axonal transport of horseradish peroxidase. Distribution of progectional fibres of neurons of the structures studied in striatum allowed to reveal its dorsal and ventral zones. Neurons of compact and dorsal parts of substantia nigra and scanty amygdala neurons project on the dorsal zone. Fibers from neurons of all the formations of substantia nigra, ventral field and of amygdala basal nucleus project on ventral field. Intersection of projections of limbic and motor subcortical formations in corpus striatum is discussed in connection with interaction of functionally different systems in it. Data obtained in dog and cat were compared.
