In the comparison of long‐distance coherence, ASD group showed increased coherence in alpha and beta bands, including F7‐F8 electrode pair in bilateral frontal regions, T7‐T8 electrode pair in bilateral temporal region, P7‐P8 electrode pair in bilateral parietal region, and F3‐O1, F4‐O2 electrode pairs in bilateral frontal–occipital region. In addition, the coherence of T7‐T8 electrode pair in ASD group was higher in theta band (Table 3).
