You do not have to act to be impulsive: Brain resting-state activity predicts performance and impulsivity on the Balloon Analogue Risk Task

Impulsivity is a key, trait-like feature of the decision-making process. As personality traits are stable over time, we hypothesized that resting-state (RS) neural activity would predict individual impulsivity. Thirty-five healthy individuals underwent fMRI scan during RS and subsequently performed the Balloon Analogue Risk Task (BART). In BART, impulsivity was inversely correlated to monetary earnings. A group-level whole-brain regression...
