BLN (basolateral amygdaloid nuclear complex) projects to ACB (Nucleus accumbens)

Method
retrograde tracer
Sign
unknown
Evidence
Some BLA neurons retrogradely labelled from the NAc also carried the CRHR1 reporter, indicating CRHR1-expressing BLA cells project to the NAc; in females a larger proportion of CRHR1 cells were NAc projectors than CeA projectors.
