Phasic mesolimbic dopamine signaling precedes and predicts performance of a self-initiated action sequence task

BACKGROUND: Sequential reward-seeking actions are readily learned despite the temporal gap between the earliest (distal) action in the sequence and the reward delivery. Fast dopamine signaling is hypothesized to mediate this form of learning by reporting errors in reward prediction. However, such a...
