Within the BF, DBh and the LPO were moderately labeled, while SI and the anterior LHy were lightly labeled (Fig. 5i–l). Collator note: Swanson Atlas Levels 16-25. SI tends to be labeled more ventrally.

The densest labeling in the prefrontal cortex is found in the ventral part of the prelimbic area. The fibers terminate predominantly in laminae I and II, and deep VI (Figs 1B, 2B, C). Collator note: Swanson Atlas Levels 8-10.
