AI (Agranular insular area) projects to BLA (basal amygdaloid nucleus)

All claims for this connection
Species
Rat
Result
present
Method
retrograde tracer
Sign
unknown
Evidence
A retrograde AAV2-retro tracer injected into the basolateral amygdala labelled neurons in the anterior agranular insula; these accounted for 34% of the labelled amygdala-projecting insular neurons. Projection-specific DREADD expression using retrograde Cre injected into the BLA also demonstrated this insula-to-BLA pathway.
Measurements
  • fraction of labelled neurons: 0.34

Named in the paper
“agranular insula (AID, AIV)” and “basolateral amygdala (BLA)”
Made by
an AI model reading the paper (claude-opus-5, extract@0.3.0), 2026-10-10
Checked by

a second AI model (claude-opus-5) agrees, 2026-10-10

“Retrograde labelling from BLA gave 34% of amygdala-projecting insular neurons, consistent with the claim.”

Status

proposed

Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
