Neural Mechanisms of Interference Control and Time Discrimination in Attention-Deficit/Hyperactivity Disorder

Our findings suggest specific but distinct patterns of cerebral dysfunction associated with interference control and TD processing in ADHD, characterized by both reduced neural activation in regions critical for task performance and reduced co-activation of frontal cortex. Group differences on the behavioral level were controlled by several methodological approaches. Nonetheless, given the use of a block design, we cannot rule out the possibility that between-group differences in behavior confounded the neural activation patterns.
