Caudal to the injection site, all layers of the dorsal half of aPI contained a dense plexus of labeled axons and terminals that continued back into aPA to roughly 2mm behind bregma (levels +1.7 to -1.8, Fig. 13). Collator note: Aip is labeled rostrally across all layers. Swanson Atlas Levels 15-26.

Collator note: Aip is labeled strong-moderate in its most caudal levels. See Fig. 13F, Swanson Atlas Level 26 (-1.8 mm from bregma).

[…] labeled fibers and terminals filled the full depth of aPI from the level of the injection site to the caudal limit of aPA at about 3.8 mm behind bregma (Fig. 15). Collator note: the rostral two thirds of the Aip are strongly labeled. See Fig 15C-D, Swanson Atlas Levels 14-19.

[…] labeled fibers and terminals filled the full depth of aPI from the level of the injection site to the caudal limit of aPA at about 3.8 mm behind bregma (Fig. 15). Collator note: the caudal part of the Aip is moderately labeled. See Fig 15F, Swanson Atlas Levels 24-25.
