Figure 17: Patient neuroimaging data: Spatial maps of group-specific reconstructed data from MSIVA $S_2$ sources related to age and SZ interaction effects.

Axial slices show the geometric median of the reconstructed data (${\stackrel{\mathbf{ˆ}}{\mathbf{X}}}_k^{\left[m\right]}$) for each modality (sMRI or fMRI) and each group (younger: 15 – 39 years, older: 39 – 65 years; control or patient). Voxel intensity is mapped to both color hue and opacity. The contours highlight the brain areas where voxelwise cross-modal correlations are significant for each group ($P<0.01$, Bonferroni correction for 44318 voxels). Scatter plots show post-CCA sources color-coded by age or diagnosis label. The reported $R^2$ indicates the proportion of variance captured by the subspace in each modality.
