Case pg353-4. 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 fibres can be seen in stria terminalis coursing rostrally from these more caudal levels. This pathway gives rise to the thalamic label reported earlier (anterior dorsal, anterior ventral thalamic nuc. and bed nuc. of the stria terminalis.).

[...] 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.
