- •
We studied the influence of reward sensitivity on behavior and brain activity.
- •
Reward sensitivity correlated with poor performance in Go trials in a Go/No-go task.
- •
Right and left IFG activity showed different roles during cognitive control.
- •
Reward sensitivity correlated with greater right and left IFG activity.
- •
Reward sensitivity mediated the association between the IFG and behavior.
