...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 substantia innominata, although most of the fibers have the appearance of fibers-of-passage, anterogradely labeled boutons and varicosities were observed reliably.
