a dense plexus of labeled axons and axonal varicosities in rostral PER, especially in the fundus and the dorsal bank of the rhinal sulcus, involving dorsal area 35 and ventral area 36 (Figs. 7B, 11D). Collator note: the terminal field is extending for a small portion in the ventral corner of the PERI in this level, and is mostly in layer III, with some extension in layer V. See Fig. 7B, Swanson Atlas Levels 33-34.

[…] labeling extended farther rostrally in this case (Fig. 7A) compared with MO (Fig. 4) and ventral VO (Fig. 6) cases. Collator note: strong-moderate label in both PERI and ECT, rostralmost. Terminals are intermingled with fibers of passage, and are distributed in layers III and V. See Fig. 7A, Swanson Atlas Levels 31-32.

Collator note: very few terminals and possible fibers of passage in the central part of the ECT. See Fig. 7C, Swanson Atlas Levels 35-36.

Collator note: few terminals in the caudalmost part of the ECT. See Fig. 7E-F, Swanson Atlas Levels 44-47.

In POR, only weak labeling was present (Fig. 7F), which is distinct from that seen in VO cases. Collator note: weak-moderate labeling in the caudalmost part of the ECT, in layers II-III. See Fig. 7F, Swanson Atlas Levels 46-47.

Collator note: few terminals in layer III in the ventral corner of the rostralmost ECT. See Fig. 8A, Swanson Atlas Levels 30-31.

Collator note: weak-moderate field in the deep layers of the PERI, and moderate-strong in the dorsal part, extending into the ECT in this level. See Fig. 11F.
