Clustering analysis results. (A) Cluster centroids for each state: state 1, less frequent but with stronger inter-connection; state 2, more frequent with relatively sparse connection. (B and C) The 3% strongest functional connections in each state are displayed, (absolute value of correlation coefficients was used), where B has edges bundled together for better characterizing connection patterns and C further shows connectivity type. The transition of colors in B means connections between networks. Red lines of C represent positive functional connectivity, while blue lines represent negative connections. SMN, sensorimotor network; VIS, visual network; AUD, auditory network; DMN, default mode network; SN, salience network; CC, cognitive control network; DAN, dorsal attention network; SC, subcortical network; CBN, cerebellar network
