- Evidence
- Anterograde EGFP tracing from the olfactory bulb labelled dense projections in both the anterior and posterior piriform cortex, which together with PRC received the highest input density among limbic cortical areas.

- Named in the paper
- “OB” and “anterior and posterior piriform cortex (APC, PPC)”
- Made by
- an AI model reading the paper (claude-opus-5, extract@0.3.0), 2026-10-09
- Checked by
a second AI model (claude-opus-5) agrees, 2026-10-09
“Anterior and posterior piriform cortex were among the densest OB anterograde targets.”
- Status
proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
