In contrast to the intramodal correlations, most intermodal correlations did not have a nearly monotonic increase from age 12 to 25, but were punctuated by a sharp decrease during ages 15 to 18 in females and ages 15 to 20 in males, followed by a recovery (see the bottom panel of Figure 2). This was the case in both correlations between modalities at the same location and correlations between modalities at different locations. Intermodal power correlations between theta EROs exhibit increases from age 12 to 25 but the only statistical significant result is for auditory Fz with visual Pz (20%) in males.
