Afferent connections of the adjoining nucleus with the amygdaloid body and dopaminergic mesencephalic structures of the cat brain

By means of the retrograde axonal transport of horseradish peroxidase and luminescent markers the data have been obtained on topical organization of projections of the basal nucleus of the amygdaloid body, of the ventral field of the operculum and of the substantia nigra nuclei to the adjoining nucleus. In the medial and lateral segments of the adjoining nucleus the terminal fields of these structures overlap and have collaterals in the nuclei of the striopallidum. The interaction of limbic and motor informations in the adjoining nucleus is discussed.
