The optimal neuroanatomical decision function used to classify FEP subject experiencing auditory hallucination (FEP‐AH) with FEP subjects without auditory hallucination (FEP‐NAH). (a) Right IPS‐Broca's complex‐left anterior insula network of CSA‐ISC in FEP‐AH. (b) ECN‐Wernicke's module complex of CT‐ISC in FEP‐AH.
