FA differences between controls (n = 68), patients with left MTS (n = 41) and patients with right MTS (n = 21).

Note the more bilateral distribution of FA alterations in patients with left MTS. When the sample of patients with left MTS was randomly reduced to n = 21, all differences observed in the full sample remained highly significant with the exception of the right parahippocampal gyrus (F = 3.15, p = 0.07).Significant at *pAbbreviations: BFL, Bilateral Frontal Lobe White Matter; BIC, Bilateral Internal Capsule; CC, Corpus Callosum; G, Genu; Hipp, hippocampus; L, Left; PHG, parahippocampal gyrus; R, Right; S, Splenium; SD, Standard Deviation; TLWM, Temporal Lobe White Matter; W, Whole.
