The images show voxel-wise spatial t maps for gray matter density reductions in PSY vs. HC, stratified by adolescent cannabis use. All between-group effects are reported at p<0.05, using cluster-wise Family Wise Error correction for multiple comparisons. The images are displayed in neurological convention; color bars indicate the ranges of t values for each between-group contrast.
PSY: volunteers with psychosis; HC: healthy controls; ACU: adolescent onset cannabis use; Non-ACU: cannabis non-users.
