Cortical thickness maps showing patterns of cortical thinning in disease groups compared to healthy controls. For each disease panel, left hemisphere sections are shown above and right hemisphere sections below. Maps are thresholded at p < 0.001 after FDR correction over the whole brain volume. The colored bar represents FDR corrected p-values. Within the LPA group, the composite map “AD/GRN overlap” codes areas in which cortical thinning was observed only in the AD-PPA group (green), only in the GRN-PPA group (blue) or in both groups (orange) relative to healthy controls at the prescribed threshold.
