The optimal neuroanatomical decision function used to classify FEP subject without auditory hallucination (FEP‐NAH) with HC. (a) Changed pattern of CSA‐ISC in FEP‐NAH: intra‐network ISC of DMN as well as inter‐network ISC between DMN versus visual, somato‐motor, salience and perisylvian language networks. (b) Differential pattern of CT‐ISC in FEP‐NAH: intranetwork ISC of DMN as well as internetwork ISCs between the DMN versus salience and language networks.
