Case pg348,349, fig5a-f. 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 Medial component of the RHT included labeled fibres and terminals found near the midline involved the medial half of the medial preoptic area terminals evident in the ventral part of the medial preoptic nucleus.

Case pg960, fig2A. Soma notes Injections larely limited to IL (5 cases) strongly labeled cells in reuniens, rhomboid, paraventricular, medial MD nuclei & sometimes labeled cells in parataenial nucleus. Terminal notes All IL injs (FB) included the dorsal peduncular cortex to varying degrees. Some also included nearaby subcortical structures. Injs largely limited to IL (n=5).

Case pg961, fig4. Soma notes LHS of thalamus had fewer cells in periventricular & anteromedial nuclei & very few cells in parataenial nucleus. Terminal notes In one IL injection, site on right side limited to layers 1 & 2 of IL, while left side also included deeper layers of IL as well as a small part of anterior cingulate cortex..

[...] 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.
