A functional connectivity matrix of the preprocessed sub-band EEG (theta, alpha, or beta rhythms) was constructed using the phase-lag index (PLI) (from zero to one). Four important variables (leaf fraction, maximal betweenness centrality (BCmax), diameter, and average eccentricity) were used to index brain network organization.
