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.).

Labeled fibers were sparsely distributed in the medial nucleus (Me) and adjacent region of the substantia innominata, medial division of the central nucleus (CeM), intercalated nucleus, and dorsomedial region of the anterior basomedial nucleus (BMA; Fig 3A). Collator note: moderate labeling of the SI in this level. The terminals tend to group dorsally. See Fig. 3A, Swanson Atlas Levels 26-27.
