This study examines age-related impairments in sensory-motor reconfiguration and pupil-linked arousal during decision-making tasks, finding reduced flexibility in switching stimulus-response mappings in older adults.

The paper investigates brain dynamics during internal decisions about stimulus-response rules, finding widespread cortical representations of internal beliefs.

The paper shows brainstem arousal systems and pupil size correlate with cortical interactions during flexible decision-making.

The paper shows that stopping rules in decision making can be learned faster using time and maximum posterior probability, suggesting Bayesian inference may be more important for animals than previously thought.
