(a) Spatial maps of six LICA components showing significant group effects. Volumetric map is presented for GMD, whereas surface maps are presented for cortical thickness and surface area. Only spatial maps of modalities with considerable contribution to the components are shown. All maps were thresholded with | z | > 3. SA = surface area, CT = cortical thickness. Whereas IC1,2,12,25 were unimodal, i.e. dominated by a single modality, IC5,8 were multimodal and driven by variation in both CT and GMD maps. (b) Subject weight distribution of the above six components. The diamond signs represent the group means. The plotted values are the residuals obtained by regressing out age and sex effects. SZ = Schizophrenia, BD = Bipolar Disorder, HC = Controls.
