Autism spectrum disorder (ASD) is a pervasive neurodevelopmental disorder with deficits in social communication and social interaction as well as restricted, repetitive pattern of behaviors, interests, and/or activities (American Psychiatric Association, 2013). According to the most recent survey, the prevalence of ASD among children aged 8 years reached 1/59 (Baio et al., 2018), which makes ASD a severe burden for whole family and society. Multiple causes are implicated in ASD, and recent imaging evidence indicates the presence of atypical brain structure and brain function during brain development. The research using structural magnetic resonance imaging (sMRI) found increased surface area for all cortical regions (Hazlett et al., 2011) and increased head circumference in the ASD group (Courchesne, 2002). Atypical brain anatomy and neurodevelopment significantly related to functional changes. The hypothesis that ASD is characterized by disrupted functional connectivity has been reliably supported by functional magnetic resonance imaging (fMRI) studies (Rane et al., 2015). Some fMRI studies observed disproportionate activation of ASD in the amygdala (Monk et al., 2010), cingulate gyrus (Shafritz, Dichter, Baranek, & Belger, 2008), fusiform gyrus (Pierce & Redcay,
