PL (Prelimbic area) projects to BLA (Basolateral amygdalar nucleus)

Species: Mouse
Result: present
Method: retrograde tracer
Sign: unknown
Evidence: Fluorescent cholera toxin B injected into the basolateral amygdala, and retrograde Cre virus injected there in other mice, labelled cortico-amygdalar neurons in PL, concentrated in layer 2 with a further group in layer 5.
Source: Rostral and caudal basolateral amygdala engage distinct circuits in the prelimbic and infralimbic prefrontal cortex
