Vertex based superficial white matter findings: Axial, Radial, Mean Diffusivity, and Fractional Anisotropy. Probability maps showing FDR corrected effects of HD on the superficial white matter Axial, Radial, Mean Diffusivity, and Fractional Anisotropy controlling for age and gender mapped at high-spatial resolution at thousands of homologous locations within the superficial white matter. The direction of effects are indicated by the color bar. Red indicates increased diffusivity with disease and blue indicates reduced diffusivity with disease. FDR, false discovery rate.
