Figure 3. Group comparisons.

z scores of mean diffusivity and fractional anisotropy plotted along the normalized length of the tracts (color-coded on the x-axis, left lower panel). Bin-wise average values of patients with temporal lobe epilepsy are compared with those obtained from the corresponding hemisphere (i.e., left or right) of healthy control subjects (0 on the y-axis represents the mean in healthy control subjects). Clusters of significant differences after random field theory correction are shown as circles. The vertical dashed lines on each graph separate the temporal (TL) from the frontal (FL) and occipital lobe (OL) portions of the tracts.
