title: Early Gamma-Band Activity During Interference Predicts Working Memory Distractibility in ADHD.
abstract: OBJECTIVE
  Patients with attention-deficit/hyperactivity disorder (ADHD) display deficits in working memory (WM) and enhanced distractibility.
  
  
  METHODS
  Evoked gamma-band response (GBR) occurs already 50 ms after stimulus onset and is modulated by attention. 16 boys with ADHD and 20 healthy controls (10-14 years) completed a WM task with distraction.
  
  
  RESULTS
  Occipitally evoked 40 Hz-GBR was higher during distraction in ADHD than controls. GBR correlated negatively with interference control.
  
  
  CONCLUSIONS
  These data suggest that ADHD patients are disturbed by interference on an early level of perception.
