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.
