Theta (A) and alpha (B and C) power for the full sample of typically developing (TD; closed bars, solid lines) and medication-naive attention-deficit/hyperactivity disorder (ADHD−; open bars, dashed lines) participants, calculated using individualized frequency bands based on peak alpha. Error bars are ±SD. A: there was no significant group difference in theta power. B: ADHD− has elevated alpha power compared with TD. *P < 0.05. C: although ADHD− had higher alpha power than TD in all tested electrodes, this group difference was not significant for any individual electrode pairs after false discovery rate correction.
