  "summary": "Staying on task, leaving it, and coming back to it are processes we experience daily. They depend on task utility and arousal, but the neurochemical processes behind this interplay are unknown. In mice performing a decision-making task with shifting reward size, we identified latent engagement states and the transitions between them. Pupil-linked arousal and dopaminergic utility coding predicted…",
