In this study, Rosenberg and colleagues identified functional brain networks whose strength in a sustained attention task predicted individual differences in performance. Using functional magnetic resonance imaging, the models predicted a clinical measure of attention, namely symptoms of attention deficit hyperactivity disorder (ADHD), from resting-state connectivity in an independent sample of children and adolescents. They suggest that whole-brain functional network strength provides a broadly applicable neuromarker of sustained attention.
