  1. Statistical difference maps of cortical thinning between psychosis (n = 40), bipolar (n = 73) and control (n = 49) groups accounting for gender and age identified in several regions of interest where p < 0.001 (uncorrected). Age-adjusted mean cortical thickness was obtained from FreeSurfer, and Cohen's d examined the difference between two means. Items of small- (d>0.2) or medium-effect size (d>0.5) are italicized. BPD, bipolar disorder group; PSY, psychosis group; CON, control group; ant., anterior; pos., posterior.
