The dorsal raphe nucleus (DRN) is emerging as a key regulator of food intake and energy expenditure but the molecular and functional heterogeneity of DRN neurons is largely unknown. A new study characterizes the role of glutamatergic DRN neurons in the control of food intake and identifies a pharmacological approach to target these neurons in obesity.
