PL (Prelimbic area) functionally connects to BLA parvalbumin-expressing interneurons

Co-staining showed essentially no overlap between the Fos signal evoked in the medial basolateral amygdala by prefrontal D1 photostimulation and parvalbumin: only about 5% of Fos-positive nuclei were PV-positive, so prefrontal D1 activation did not appreciably recruit these interneurons.

Made by an AI model reading the paper (claude-opus-5, extract@0.3.0); a second AI model (claude-opus-5) agrees.
