[Projections of the amygdaloid body and dopaminergic mesencephalic formations to the entopeduncular nucleus of the cat brain].

Organization of projections on entopeduncular nucleus different regions from amygdala and from nuclei of tegmental ventral field and black substance was studied in cat using retrograde axonal transport of house radish peroxidose. Analysis of the labelled neurons distribution in these structures in separate marker injections into the rostral and caudal segments of entopeduncular nucleus allowed to conclude that projective fibres to rostral region come from not numerous neurons of tegmental ventral field and black substance compact part, and to caudal one apart from these structures neurons--also from scanty neurons of dorsal and lateral parts of black substance. Projections on entopeduncular nucleus from amygdala were not found.
