Statistical analyses were performed including age, gender, education level, total GM volume and centre as nuisance covariates, with a threshold of P = 0.05, FWE or P = 0.001, uncorrected, including a minimal k of 50 voxels

GM grey matter, FCSRT Free and Cued Selective Reminding Test, VBM voxel-based morphometry, L left, R right, BA Brodmann area, k cluster size in voxel (specific region’s volume/cluster’s global volume), x, y, z Talairach coordinates, T T value, g. gyrus, DTR delayed total recall, FR free recall, FWE family-wise error, TR total recall
