Webinternal network: small-worldness. ‘‘Small-world’’ originates from a famous experiment (Milgram, 1967) that showed ‘‘six degrees of separation.’’ As deﬁned by Watts and Strogatz (1998), ‘‘…the systems can be highly clustered, like regular lat-tices, yet have small characteristic path lengths, like WebEvidence suggests that the small-worldness of functional connectivity undergoes successive topological changes with various cognitive loads. This process is based on neuroplasticity, the ability to rapidly grow and reorganize distributed neural networks ranging from new pathways among individual neurons to routine adjustments [16,17].

WebMar 31, 2024 · smallworldness (x, B = 1000, up = 0.995, lo = 0.005) Arguments Details The function computes the transitivity of the target network and the average shortest path length. Then it computes the average of the same indices on B random networks. WebSmall-worldness is commonly measured with the coefficient sigma or omega. Both coefficients compare the average clustering coefficient and shortest path length of a given graph against the same quantities for an equivalent random or lattice graph.
