In the preoptic regions, relatively sparse numbers of marked cells were observed in the median preoptic, anteroventral periventricular, medial preoptic, anterodorsal preoptic, anteroventral preoptic, and parastrial nuclei, as well as in the undifferentiated part of the medial preoptic area. In addition, a very few retrogradely labeled neurons were noted in the lateral preoptic area (Fig. 3C-F).

Several BSTtr axons also generate a nearby terminal plexus in a dorsomedial region of the lateral hypothalamic area between the fornix and anterior parvicellular part of the paraventricular nucleus (Fig. 6G–J).

Descending BSTtr axons in the ventral pathway generate a few branches and boutons in the retrochiasmatic area (Fig. 6J–L) before arching dorsomedially to provide a dense, vertical terminal field in a restricted zone of the lateral hypothalamic area between the fornix and tuberal nucleus at the level of the ventromedial nucleus (Fig. 6N–R).

[...] many PHAL–labeled BSTtr axons that course through the BSTif, BST ventral nucleus, and caudal substantia innominata enter rostromedial regions of the lateral hypothalamic area (Fig. 6I,J), where they display some branching and boutons.

At the level of the dorsomedial nucleus many axons in the medial forebrain bundle turn medially and generate a rich terminal field in a restricted suprafornical region of the lateral hypothalamic area between the zona incerta and fornix that extends medially into the anterior part of the dorsomedial nucleus (Figs. 6O–P, 7D'').
