Figure 1.
ROIs location for PCC and dACC.
The coherence values between the BOLD signals from these two areas are used as predictors to the classifier.
Figure 2.
Typical development and ADHD patients’ median coherence (and 75% quantiles – dotted lines) and boxplots of the abnormality indexes of pairwise comparisons between groups.
These indexes show that ADHD patients have a similar pattern of young TD and both differ from TD-matched controls.
Figure 3.
Discriminative relevance of each frequency in groups comparison.
The frequencies below 0.05 and around 0.20 Hz contain most discriminative information.

ADHD-200 Sample: Boxplots of the abnormality indexes of pairwise comparisons between groups at different ages.
Bottom-right: relevance of each frequency in discriminanting ADHD patients from TD age-matched controls. These findings are very similar to the ones obtained in the adults dataset.
