This study finds that spontaneous eye blink rate (sEBR) predicts individual differences in exploration and exploitation during reinforcement learning, specifically linking lower sEBR to exploitative choices and higher sEBR to exploration.

This study shows that dopaminergic medication in Parkinson’s disease reduces striatal sensitivity to negative outcomes during learning and affects subsequent approach/avoidance behavior.

This study shows that visual cortex activity predicts future value-based choices, suggesting a role for visual regions in supporting striatal bias during decision-making.

The paper shows that feedback activity in the brain increases during object recognition in complex natural scenes, improving performance, while feed-forward processing suffices for simpler scenes.

This study uses pupil responses to track value-based decision-making and reinforcement learning during a task, finding distinct patterns linked to value beliefs and reward prediction errors.

The paper investigates how fronto-basal ganglia circuitry contributes to response inhibition and conflict-induced slowing using fMRI and reinforcement-learning models.
