Fig. 5. Results of VBM (A) and DTI (B) covariation analyses for the average SICI. Results for ALS and bvFTD are shown in light-blue/dark-blue and yellow/red shading, respectively. Colored voxels show regions that were significant in the analysis at p<0.05 with correction for the false discovery rate (FDR). For all clusters, t>3.50. Clusters are overlaid on the MNI standard brain atlas. ALS: amyotrophic lateral sclerosis, bvFTD: behavioral-variant frontotemporal dementia, DTI: diffusion tensor imaging, MNI: Montreal Neurological Institute coordinates, SICI: short-interval intracortical inhibition, VBM: voxel-based morphometry.
