Neural correlates of intrasubject variability (ISV) were studied using functional magnetic resonance imaging in 25 children with attention-deficit/hyperactivity disorder (ADHD) and typically developing(TD) children performing simple go/no-go tasks. Results concluded that in children with ADHD, dysfunction of premotor systems resulted in increased variability and impaired response inhibition, and that using strategies that increased cognitive control can improve function.
