This study examines how intolerance of uncertainty affects behavioural flexibility in a reversal learning task, finding associations with reinforcement sensitivity and performance following reward changes.

This study shows a direct link between platelet reactivity and neurovascular function in older adults, independent of vascular reactivity, suggesting a novel mechanism in early dementia pathophysiology.

This study examines the relationship between the resting state of the dorsal striatal cholinergic system and flexible behavior in reversal learning, finding variability in choline levels correlates with error rates and learning speed.

This study investigates corticostriatal and thalamostriatal connectivity during serial reversal learning, finding increased functional connectivity between the centromedian-parafascicular nuclei and striatum for negative feedback.
