(A) Results of the frequency-band specific analysis of significant (p < 0.05) coherent sources. On the source level, healthy children showed stronger source mean power and coherence values in theta, alpha and gamma frequency bands compared to patients with ADHD. (B) Illustration of information flow between sources (same source naming as in (A) of brain activity for each frequency band. The directed within-group coherence analysis indicated significantly stronger information flow from frontal to parietal sources in control children for same frequency bands. In addition, thalamo-cortical connectivity was unidirectional (i.e., outflow from cortical regions) in ADHD group, but bidirectional in NTC group for the alpha, beta and gamma frequency bands.
