Synchronized change rates of cortical MK and associated WM FA. (A) Three-dimensionally reconstructed WM tracts traced from the four clusters shown in Fig. 3B. These tracts were identified as cingulum in cingulate gyrus (purple; traced from cluster 1), forceps major (blue; traced from cluster 2), inferior longitudinal fasciculus (green; traced from cluster 3), and uncinate fasciculus (red; traced from cluster 4). (B) Synchronized cortical MK change rates (blue triangles) and associated WM FA change rates (black circle; shown in mean and SD) of the four clusters. Significant differences between FA change rates of any two of these four WM tracts were found, except between FA change rate of WM tract associated with clusters 2 and that associated with cluster 3. *P < 0.05; **P < 0.001.
