Fig 1. Ventral striatal activity is related to task performance.

There was a positive correlation between activation in ventral striatum and the shift in reaction time distribution (B_0vs15ct) (FWE corrected for multiple comparisons). Both panels display the T-map of a single-factor ANCOVA with B_0vs15ct as continuous predictor variable. Panel A shows the effect of task performance on the activation difference between low and high reward conditions. Panel B shows the effect of task performance on the activation difference between no reward and high reward conditions.
