In contrast, in the controls, we found a widespread bilateral cortical WM network where the FA level showed a highly significant positive correlation ( r = 0.79) with perceptual TCs [Fig. 4 C ; t max = 5.52, P < 0.05, size = 40 145 voxels ( x = 26, y = −28, z = 28 mm); corrected for multiple comparisons], with the cluster maximum in the right temporo-parietal WM.
