BLN (basolateral amygdaloid nuclear complex) projects to Pir (piriform cortex)

Species: Rat
Result: present
Method: anterograde tracer
Sign: unknown
Evidence: After AAV5-CaMKIIa-eArchT3.0-eYFP was infused into the BLA, YFP-labelled axon fibres from the BLA were seen within the posterior piriform cortex. Optical fibres were then aimed at these terminals in the pPCX.

Named in the paper: “basolateral amygdala (BLA)” and “posterior piriform cortex (pPCX)”
Made by: an AI model reading the paper (claude-opus-5-5, extract@0.3.0), 2026-10-09
Checked by: a second AI model (claude-opus-5-5) agrees, 2026-10-09
“The Fig. 6A caption reports YFP-labelled BLA fibers inside the pPCX after AAV-eYFP infusion into the rat BLA, which amounts to anterograde viral labelling of this projection.”
