BLN (basolateral amygdaloid nuclear complex) projects to AI (Agranular insular area)

Species: Rat
Result: absent
Method: retrograde tracer
Sign: unknown
Evidence: Retrograde AAV2-retro-tdTomato injected into the agranular posterior insula produced no visible labelled neurons in the BLA.

“The agranular pIC retrograde injection produced no visible BLA labelling, supporting an absent result in Fig. 3D.”
Status: proposed
Drafted and checked by AI models; it stays proposed until people have audited a sample of such claims.
