FIG. 4.

Three-dimensional (3D) maps of statistically significant differences in diffusion tensor imaging parameters between all three experimental groups. Voxel clusters with an adjusted p value less than 0.05 are displayed as 3D, colored surfaces within a transparent surface rendering of the entire brain. Statistically significant differences in fractional anisotropy (red) and radial diffusivity (green) are shown for each pair of experimental groups. The left-most column contains anatomical references including an opaque surface rendering of the entire brain (top) and a single horizontal slice of the average anatomical image volume (bottom).
