FIGURE 3.
Changes in gray matter volume in different brain areas after intervention. The axis of ordinate displays changes based on β parameter estimates (with 90% confidence intervals) of the peak voxels within the respective clusters. As a region of interest (ROI), we compared pre- and post-intervention contrasts between the three groups to eliminate the possibility of pre-intervention differences in GMV: (post_ExM > pre ExM) > (post_Cont > pre_Cont) and (post_Ex > pre_Ex) > (post_ Cont > pre_Cont).
