In the comparison of short‐distance coherence, the coherence of bilateral temporal–parietal regions T7‐P7 and T8‐P8 electrode pairs was higher in ASD group in all frequency bands. In the comparison of coherence in occipital region, children with ASD showed increased coherence of O1‐O2 electrode pair in theta, alpha, and beta bands. And ASD group had an increased coherence of right central–parietal C4‐P4 electrode pair in delta, alpha, and beta bands. In the comparison of coherence in prefrontal region, Fp1‐Fp2, Fp1‐F3, F3‐F4, and Fp2‐F4 electrode pairs had increased coherence in beta band (Figure 2, Table 3).
