A Distinct Subpopulation of Extended Amygdala Neurons Drives Food Intake

BACKGROUND: Neurons in the oval subnucleus of the bed nucleus of the stria terminalis (ovBNST) integrate stress and reward signals to regulate motivated behaviors, including food consumption. However, the contribution of specific ovBNST neuronal subpopulations remains poorly understood. Here, we investigated vasoactive intestinal peptide receptor 2 (Vipr2) expressing ovBNST neurons using chemogenetics, immunohistochemistry, and viral circuit mapping.
