Researchers explored how mice time their actions to receive rewards, focusing on the mesocortical brain pathway. The study found that dopamine-mediated signals via D2 receptors are crucial for self-initiated movements. These signals increase activity just before action but not in response to cues. The findings enhance our understanding of goal-directed behavior and its underlying brain mechanisms.
