Whole-brain input mapping of the lateral versus medial anterodorsal bed nucleus of the stria terminalis in the mouse

MEA (Medial amygdalar nucleus) MBA:403 projects to BST (Bed nuclei of the stria terminalis) MBA:351 · Mouse

CAV2-Cre tracing showed medial amygdala input to lateral adBNST. This input was much smaller than the medial amygdala input to medial adBNST.
