Case pg524, fig1. Soma notes 6 rats (3 albino and 3 hooded) were used. Intraocular injection of [3H]leucine. Terminal notes The projection to the internal division of the VGL is comparitively sparse we have also found that an ipsilateral retinal projection is present in the VGL in the albino rat as well as the hooded rat.

Proceeding caudally, moderate numbers of marked cells were also noted in a region in the zona incerta that was continuous with substantial retrograde labeling in the medial zone of the ventral geniculate nucleus, where relatively small numbers of marked neurons also appeared to extend into the lateral zone in addition to the intergeniculate leaflet of the lateral geniculate complex (Fig. 3L, M).

At the anterior hypothalamic level, ascending fibers coursing through the hypothalamus supply dense inputs to the anterior hypothalamic nucleus, subparaventricular zone, rostral retrochiasmatic area, and perifornical region of the lateral hypothalamic area in addition to a relatively sparse input to the other regions of the lateral hypothalamic area (Figs. 5D–G, 6B).

Proceeding rostrally, large numbers of fibers from the PRC reach the preoptic region, where they appear to provide a dense input to the lateral preoptic area in addition to a sparse input to the anteroventral preoptic nucleus (Fig. 5B,C).
