PB (Parabrachial nucleus) projects to CEAc (Central amygdalar nucleus, capsular part)

Species: Mouse
Result: present
Method: anterograde tracer
Sign: unknown
Strength: strong
Evidence: Cre-dependent mCherry and synaptophysin-GFP viruses injected into the PBN of CalcaCre mice labelled abundant axons and presynaptic terminals in the laterocapsular central amygdala, overlapping with CGRP immunostaining of terminals there.
Source: Genetic identification of a neural circuit that suppresses appetite

Named in the paper: “PBelo (CGRP neurons)” and “CeAlc (laterocapsular division of the central nucleus of the amygdala)”
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
“Dual AAV anterograde labelling showed dense mCherry/Syn-GFP fibers in CeAlc overlapping CGRP terminals.”
Status: proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
