This study investigates how dopamine modulates striatal activity during working memory output-gating using fMRI and finds that sulpiride alters striatal activity and reduces neural stimulus selectivity in visual cortex, affecting task performance.

The paper investigates whether simple trait measures correlate with striatal dopamine synthesis capacity and finds no significant correlations.

The study replicates a previous finding that reward effects on cognitive control depend on dopamine synthesis capacity but fails to find a correlation in a larger sample using a different radiotracer.

This study shows methylphenidate increases preference for mental labor over leisure, especially in individuals with higher baseline striatal dopamine.
