White matter correlates of reduced emotion identification performance in both patient groups (top panels), the bvFTD group alone (middle panels) and the svPPA group alone (bottom panels). Results are overlaid on a customised group template brain image and displayed in MNI standard space; the right hemisphere (R) is displayed on the left. The colour scale indexes p-value after family-wise error correction over the whole brain at p < 0.05. Key: AX, axial diffusivity; bvFTD, behavioural variant frontotemporal dementia; RD, radial diffusivity, svPPA, semantic variant of primary progressive aphasia.
