...at the anterior hypothalamic level, the rostral pole of the anterior hypothalamic nucleus presented a dense cluster of retrogradely labeled cells distributed in a region that seems to overlap with a territory known to contain large numbers of neurons expressing enkephalin (Harlan et al., 1987), whereas the caudal two-thirds of the nucleus contained relatively sparse numbers of marked cells (Fig. 3D–I).

In the septal region, moderate numbers of anterogradely labeled axons were observed in the nucleus of the diagonal band, medial septal nucleus, and dorsal region of the ventrolateral zone of the rostral part of the lateral septal nucleus (LSr.vl.d; Fig. 5A,B).
