Fourth, several nuclei of the hypothalamus project to the BSTvl; these inputs originate from the medial preoptic region (Figs. 4D,E, 5C), arcuate nucleus (Figs. 4G–J, 5I), dorsomedial hypothalamic nucleus (Fig. 4H,I), lateral hypothalamic area (Figs. 4F–L, 7D), parasubthalamic nucleus in the dorsolateral hypothalamus (Figs. 4K,L, 5H), and posterior hypothalamic nucleus (Fig. 4K,L). Collator note: see Figure 4D-E. In Figure 4, the level of the injection site, the entire part of the tissue, which is medial to BSTvl, is labeled more or less uniformly, with a "halo" of intense signal just around the nucleus (BSTdm and fu). See Atlas Levels 19.

The PHAL-labeled axons idistributed dense TB and BP in the rostro-ventral area of SI, which is refered as "pan handle" in Paxinos and Watson.

Two terminal fields were observed, one is continuation of that from the rostroventral regions of the SI, the other is caudodorsal regions of the SI.
