All significant regional grey matter associations of performance on verbal generation tasks from the VBM analysis of the combined patient cohort are shown. Coordinates of significant local maxima are in Montreal Neurological Institute standard stereotactic space; all regions are in the dominant (left) hemisphere. Significance has been thresholded at p<0.05 after family-wise error correction for multiple voxel-wise comparisons within pre-specified anatomical regions of interest.
