Investigating brain electrical activity and functional connectivity in adolescents with clinically elevated levels of ADHD symptoms in alpha frequency band.

EEG measures such as power and connectivity have been widely used to investigate the neuronal underpinnings of ADHD. Traditionally, the fixed band analysis, in which a single frequency band is applied to all the subjects, has been used to estimate these EEG measures. However, there are important interindividual differences in the predominant frequency of alpha-band oscillations.
