The variability of EEG functional connectivity of young ADHD subjects in different resting states.

Objective: To assess ADHD from global measures of EEG functional connectivity and their temporal variability in different resting states.

Methods: EEGs from sixteen cortical regions were recorded at rest during eyes-closed (EC) and eyes-open (EO) in 10 male combined-type ADHD subjects and 12 healthy male controls. The mean global connectivity (CM) of each region and its temporal variability (CV) were estimated from a number of EEG segments recorded in both states.
