Fig. 2: Findings of clustering analysis.

a Cluster centroids of each state. Two states, a more frequent (around 75% of total occurrences) and sparsely connected State 1, and a less frequent (around 25% of total occurrences) and more strongly interconnected State 2. b Top 100 of the functional connectivity in each state, representing the strongest connections (i.e., the absolute value of correlation coefficients). Each color represents one of the six networks. Between-network connections were indicated by a transition of colors between the two networks.
