A brainstem to hypothalamic arcuate nucleus GABAergic circuit drives feeding.

ABSTRACT: The obesity epidemic is principally driven by the consumption of more calories than the body requires. It is therefore essential that the mechanisms underpinning feeding behavior are defined. Neurons within the brainstem dorsal vagal complex (DVC) receive direct information from the digestive system and project to second-order regions in the brain to regulate food intake. Although γ-aminobutyric acid is expressed in the DVC (GABA^DVC), its function in this region has not been defined. In order to discover the unique gene expression signature of GABA^DVC cells, we used single-nucleus RNA sequencing (Nuc-seq), and this revealed 19 separate clusters. We next probed the function of GABA^DVC cells and discovered that the selective activation of GABA^DVC n
