Case pg352. Soma notes 36 female Sprague-Dawley rats weighing 200-350g. 10 microliters of CT-HRP(.20%-.40%) were injected into one eye ?behind the lens into the vitreous chamber of the eye. pressure injection over 1 min. Terminal notes Med. component of the RHT?in addition, labeled fibres and terms were found lateral to the lateral boundary of the SCN, in the lateroanterior hypothalamic nucleus. Lat component diffuse labeling in the lateroanterior hypothalamic nucleus was evident.

Some labeled cells were present in the mesencephalic PAG, rostrally (Fig. 8o, p) as well as caudally (Fig. 8t). Collator note: caudally (Swanson Atlas Level 41), there is a single neuron labeled in PAGvl. Very weak at best.

[...] principal target was the lateral hypothalamic area, in particular its ventrolateral and perifornical regions (Figs. 3D-G, 5C,D). Although innervation of the anterior part of the lateral hypothalamic area was scant, varicose fibers running in a mediolateral direction were prominent in the retrochiasmatic area.
