VBM results of 47 Helsinki patients. Time (Acute >6 months) × Group (NRAs > NAs) in GMV or WMV interaction. A, GM NRAs (N = 16) versus NAs (N = 18). B, GM (hot) and WM (cold) nonrecovered rhythm amusics (N = 11) versus nonrhythm amusics (N = 18). C, GM nonrecovered pitch amusics (N = 13) versus nonpitch amusics (N = 17). Bar plots for GMV differences in Acute >6 months. Bar, mean; error bar, SEM. The results are reported at an uncorrected p < 0.001 threshold at the voxel level (extent threshold: k > 50 voxels) using MNI coordinates. Clusters for analysis A and B pass a p < 0.05 FWE-corrected threshold at the cluster level.
