(A) Psychophysiological interaction (PPI) seed region in midbrain and statistical parametric map (SPM) of PPI group negative effect in subjects with ultra high risk (UHR) that did transfer into psychosis (UHR-t) > subjects with UHR that did not transfer into psychosis (UHR-nt) in prefrontal cortex (P < .05 cluster corrected) and plots showing significantly greater negative (word repetition > verbal fluency) PPI contrast estimates in UHR-t subjects in (B) left superior frontal gyrus, and (C) right middle frontal gyrus.
