...a cluster of marked cells was found in the lateral hypothalamic area immediately dorsal to the supraoptic nucleus, in a region that seems to overlap with the main site of projection of the lateral component of the retinohypothalamic tract (Figs. 3F,G, 4C).

In one experiment, a PHAL deposit was virtually confined to the region densely targeted by the lateral component of the retinohypothalamic tract, which was labeled in the same experiment with a CTb deposit in the contralateral eye, and a dense plexus of PHAL anterogradely labeled fibers could be observed in the PMd (Fig. 6).

...at caudal levels of the anterior hypothalamic nucleus, a prominent cluster of labeled cells was also found just ventral to the fornix in the intermediate region of the lateral hypothalamic area (Figs. 3H,I, 4A).

...at caudal levels of the tuberal region, a cluster of retrogradely labeled cells was also found in the lateral hypothalamic area, immediately ventral to the fornix (Fig. 3K).
