FIG. 6.

Tractography-based analysis of diffusion tensor parameter differences between all three experimental groups. Statistical significance and effect size for each comparison (columns) are shown as colored tractography streamlines with hotter colors indicating increased statistical certainty (adjusted p value maps) or increased effect size (effect size maps). Anatomical references are included at the bottom of the figure including directionally colored tractography streamlines (left) and a horizontal slice of the anatomical image volume (right). Labeled structures are: cerebellar white matter (cbw); forceps major of the corpus callosum (fmj); cingulum bundle (cg); inferior, middle and superior cerebellar peduncles (icp, mcp, and scp respectively). FA, fractional anisotropy; RD, radial diffusivity. Color image is available online at www.liebertpub.com/neu
