Metabolic sensing in AgRP neurons integrates homeostatic state with dopamine signalling in the striatum

eLife, 2022
Agouti-related peptide (AgRP) neurons increase motivation for food, however, whether metabolic sensing of homeostatic state in AgRP neurons potentiates motivation by interacting with dopamine reward systems is unexplored. As a model of impaired metabolic-
