The goal of this observational study is to learn how brain activity in children with autism spectrum disorder (ASD) differs from typical developing children using magnetoencephalography (MEG). The main questions this study aims to answer are: Do children with ASD show different patterns of neural oscillation compared to typically developing children? Can MEG identify specific brain features that help ASD diagnosis? Participants will undergo MEG scan in both resting and tasking state, and their brain activity will be analyzed for characteristic neural oscillations and connectivity patterns. This study may help develop better tools for early ASD diagnosis.
