Dopamine: It's not just for rewards anymore. In a new Northwestern University-led study, researchers identified and recorded from three genetic subtypes of dopamine neurons in the midbrain region of a mouse model. Although there is a long-standing, common assumption that most — if not all — dopamine neurons solely respond to rewards or reward-predicting cues, the researchers instead discovered that one genetic subtype fires when the body moves. And, even more surprisingly, these neurons curiously do not respond to rewards at all.
