Case pg329-30, fig6D,11. Soma notes ?supramammillary region ?projects to pregenual field; pathways predominantly uncrossed & non-dopaminergic. Most cells that give rise to these projections found in VTA & supramammillary region. --Fig11: moderate; Table2: 37% of all labeled cells in SUMm-. Terminal notes In 10 expts, pregenual field injecte with either true blue (9) or bisbenzimide (1); in several brains 2 large injection of true blue were made, to label maximally terminal field. Results of expt VTA91 representative of this group..

Labeling was much more pronounced at the caudal than rostral hypothalamus, densest within the SUM (Figs. 8o, p, 9c). Collator note: Swanson Atlas Levels 36-37. A band of labeled cells extends dorsoventrally, close to the midline, crossing the PAG, PH, and ending in the SUMl where it extends laterally.

[...] 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.
