The prefrontal cortex is the core area of the "social brain" (Dunbar, 1998). The activation of prefrontal cortex is associated with cognitive control tasks, and frontal lobe dysfunction is related to social, emotional, and cognitive impairment in ASD (Rajak et al., 2018). In present study, the hyperconnections in prefrontal region, bilateral temporal–parietal, were not related to social and cognitive ability in children with ASD. Children with ASD showed excessive connections in the prefrontal lobe, which means more neurons were activated during social information processing, and further result in cognitive, social, and emotional dysfunction. The temporal lobe is responsible for processing auditory information. Our results showed that children with ASD had increased local connections in bilateral temporal–parietal regions (T7‐P7, T8‐P8). The spatial location of P7 and P8 electrodes is related to Wernicke's region. Wernicke's region is the center of language understanding. It might indicate that children with ASD have difficulty in language comprehension when they deal with auditory information.
