Figure 5 shows the topographical map of mean global efficiency, local efficiency, and mean clustering coefficient values of middle-aged and elderly groups in the eyes-open state. All three network parameters show differences in the whole brain network in different brain regions. In the eyes-closed state, mean local and global efficiencies and clustering coefficients clearly show differences, as shown in Figure 6. During the visual WM task, differences can be seen in local efficiency, global efficiencyas well as in clustering coefficient, as shown in Figure 7.
