All peak values reported were significant at p < 0.005 (uncorrected); 60 voxels spatial extent. Correlation coefficients (r) were calculated with the voxels comprising each cluster. For slope measure FA/s, s refers to the regressed memory scores. Peak coordinates of each cluster are reported in Montreal Neurological Institute coordinates. IFO, Inferior fronto-occipital fascicle; R, right; L, left.
* indicates regions that showed p values false discovery rate corrected at the whole-brain level (p < 0.05) and at the cluster level (p < 0.001).
