Table 1.

Mean values, standard deviations (SD) and coefficient of variation (CV) across individuals of the different microstructural metrics, calculated on the eight different reconstructed tracts (data for left and right are averaged): the arcuate fasciculus (ARC),the cingulum (CING), the uncinate fasciculus (UNC), the superior longitudinal fasciculus (SLF), the inferior longitudinal fasciculus (ILF), the inferior fronto-occipital fasciculus (IFOF), the fornix (FX) and the thalamo-cortical (TC) tract. MD, AD, RD and IAD are expressed in units of 10^− 3 mm²/s. T1 and T2 are expressed in ms. CV is expressed in percentage.
