Correlation analysis shows that increased short‐distance connection in the occipital area (O1‐O2) was positively correlated with symptom severity, which is supported by imaging evidence (Nair et al., 2018). The occipital striate area is the central visual cortex as well as the end of the nerve fibers that transmit information from the retina. The pattern of excessive connection of occipital striate area may be the characteristic change in children with ASD and be correlated with symptom severity. Furthermore, Carson et al. (2014) found that the abnormal coherence in alpha band was related to priority attention to details in children with ASD. In present study, we found that there was a positive correlation between left frontal–occipital, frontal region, and right temporal–parietal region and attention to details of AQ in beta band. Consequently, the abnormal connection pattern of children with ASD may be a neurophysiological basis for their clinical symptoms even though the results of the previous studies were not consistent.
