Community structure of macaque resting-state fMRI networks. A, The functional network partitioned into four modules. Node ordering as specified in Table 2. B, Functional community structure projected onto the F99 surface. Modules 1 (yellow), 2 (gray), 3 (green), and 4 (blue) as outlined in Table 2. C, Rank-ordered functional participation coefficients for positive weights in left hemisphere. Right hemisphere data were similar (data not shown). Nodes identified as hubs in the structural network using apex ratio are denoted by red bars (Fig. 7). * denote structural hubs identified using degree measures. ** denote structural hubs identified using both degree and betweenness centrality measures. For abbreviations, see Table 1.
