WebNov 1, 2013 · Structural brain networks exhibit small-worldness and modularity . Small-worldness indicates a short average path length between all node pairs, with high local clustering, whereas modularity denotes dense intrinsic connectivity within a module but sparse, weak extrinsic connections between modules. WebThis study aimed to investigate the topological characteristics of the resting-state functional network and the underlying pathological mechanism in nondialysis patients with stage 5 chronic kidney disease (CKD5 ND).
