  1. Alpha, power of periodic oscillations in the alpha (7–13 Hz) band; Beta, power of periodic oscillations in the beta (14–25 Hz) band; TD, typically developing children; ASD, children with autism spectrum disorder; and TD + ASD, combined sample of the children
  2. #p < 0.1; *p < 0.05; **p < 0.001
