Δ: Change; FA: fractional anisotropy; − not available (as TFCE correction does not result in t values and associated degrees of freedom)

^*FWE Corrected P < 0.05

^**FWE corrected P < 0.0166 (corrected for 3 imaging contrasts/comparisons)

^†TFCE corrected P < 0.0083 (corrected for 6 imaging contrasts/comparisons)
