Goal-directed behavior requires the coordinated activity of sensory and motor areas across the brain. Recent advances in large-scale neural recordings allow studying brain-wide dynamics during behavior at cellular resolution. We used mesoscale calcium imaging to record the activity of up to ~30,000 neurons simultaneously (~1,000,000 neurons total) from over 10 cortical areas while mice performed a novel goal-directed naturalistic behavior. The behavior consisted of multipositional tongue-reaching movements to a target to obtain a water reward, with the target presented on a grid (typically con
