Voxel-wise statistical analysis of grey matter damage: overall object naming and the shared language component. Note: VBM results showing voxels corresponding to grey matter damage in (red) overall object naming, (yellow) the ‘shared’ language principal component and (orange) their overlay. Please note that the lesioned areas are coloured according to their significance level in the VBM analysis, where brighter colours mean higher t-values. The numbers in brackets indicate peak MNI coordinates. Rows (1) & (2) show the neural correlates of the results in different views of the brain. Across each row, the first two images are T1-weighted MR images overlaid with statistical parametric maps (SPMs) generated from the VBM analyses. In addition, to further illustrate the possible use of CT scans in lesion–function mapping analysis, SPMs are plotted on CT images (the right-most image across each row) of the same axial views. IFG, inferior frontal gyrus; STG, superior temporal gyrus; FG, fusiform gyrus; POG, posterior occipital gyrus.
