In neurotypical adults, mind-wandering (MW) is associated with increases in posterior alpha power, reflecting inward-directed mentation, but tonic, cortical arousal remains largely unexplored in adults with attention-deficit/hyperactivity disorder (ADHD), particularly prone to MW. The main aim of this study was to characterize stimulus-independent oscillatory activity during MW and determine how global and spatially localized MW-related cortical arousal differs between ADHD patients and…
