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.

Collator note: several labeled nuclei dispersed in the ventromedial zone of the caudal PAGvl (Swanson Atlas Levels 45-47).

[...] 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.
