BLN (basolateral amygdaloid nuclear complex) functionally connects to PVH (Paraventricular hypothalamic nucleus)

All claims for this connection
Species
Rat
Result
present
Method
optogenetic circuit mapping
Sign
unknown
Evidence
Photostimulating BLA CaMKII neurons increased FOS density in the paraventricular hypothalamic nucleus compared with mCherry controls; the authors interpret this as indirect activation since the BLA lacks a direct PVN projection.
