Figure 4
Psycho-physiological interaction analysis. Panel A visualizes the group difference in effective connectivity of right STS (purple) with a cluster in medial prefrontal cortex (mPFC) (blue-green) during explicit biological motion processing (>fixation). The right panel visualizes the psycho-physiological interaction for an exemplary participant of the ASD and TC group. Panel B visualizes for each group (ASD, TC) the relationship between coupling (effective connectivity) of right STS with mPFC and parameter estimates of task-related brain activity in right STS (explicit > fixation). Panel C visualizes for each group (ASD, TC) the relationship between coupling (effective connectivity) of right STS with mPFC and discrimination sensitivity (d’).
