Evidence
Synaptophysin-mCherry tracing from AVPR1A CeA neurons labelled boutons in the mesencephalic reticular formation; rabies-based collateral labelling of DLS-projecting AVPR1A CeA neurons also revealed axons there.

Named in the paper
“AVPR1ACeA neurons” and “mesencephalic reticular formation (mRT)”
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

“mRT is listed as a prominent target and as a collateral site.”
