Figure 4.
Representative number of ROIs overlaid onto axial group mean FA images for FH− and FH+ youth. Most ROI analyses confirmed TBSS results and fell in areas of high FA representing white matter tracts in both groups (a & b). Inset pictures qualitatively show how partial volume effects are different between the groups and may contribute to significant group differences for the particular ROIs in the parietal and inferior temporal lobe (e, f, g, h).
