This story is about a Nature Neuroscience study on how acetylcholine may help separate dopamine signals tied to learning from those tied to movement. In rats doing a decision task, the paper reports that the timing between acetylcholine dips or bursts and dopamine release in the dorsomedial striatum seemed to matter: when dopamine followed cholinergic dips it tracked later learning, and when it lined up with cholinergic bursts it predicted movement vigor.
