Atypical dynamic brain activities (dBAs) of people with autism spectrum disorder (ASD) were reported related to ASD symptoms. However, the most commonly used dynamic function connectivity method is affected by sliding window size. In this study, co-activate pattern analysis which keeps high temporal resolution and without the limitation of window size, is used to evaluate dBAs. It is found that the atypical dBAs of ASD is related to ASD core symptoms, and the atypical dBAs pattern of ASD is also affected by age.
