A hypothalamic circuit links hunger to mesolimbic dopamine to drive feeding
Hunger enhances the motivational value of food, but the neural circuits linking homeostatic hunger neurons to dopamine systems remain poorly understood. Here, we identify a hypothalamic-midbrain neural circuit through which AgRP neurons engage the mesolimbic dopamine system. We demonstrate that AgRP neuron activity is both necessary and sufficient for the potentiated dopamine response to food by…
