On the other hand, we found the excessive long‐distance connections in frontal region, temporal region, parietal region, and frontal–occipital region, which was inconsistent with many studies about the reduced long‐distance connection (Khan et al., 2013; Kikuchi et al., 2015). Aberrant brain long‐distance connections were reported in autistic children (Coben, Clarke, et al., 2008; Duffy & Als, 2012), adolescents (Lajiness‐O'Neill et al., 2014), and adults (Leveille et al., 2010; Mathewson et al., 2012; Saunders, Kirk, & Waldie, 2016). However, there is no consistent conclusion about brain long‐distance connection patterns in different autistic age groups. A recent fMRI study provided an imaging evidence for our findings (Supekar et al., 2013). It pointed out that the hyperconnectivity was observed at the whole‐brain and subsystems level, across long‐ and short‐range connections in a large sample with 110 children with ASD, and children with more severe impairment in the social domain exhibited increased functional connectivity. Therefore, the aberrant short‐/long‐distance connectivity may be associated with pathogenic mechanisms in children with ASD. Long‐distance connectivity is a higher‐level brain activity, which rapidly integrates information in different brain areas
