Correspondence of FC state time-courses with the FCD matrix and relationship with SC. (A) The time-versus-time FCD matrix (top) from one representative subject is compared with the corresponding FC state time-courses given by the k-means clustering algorithm (bottom). Note that each red square in the FCD matrix can be associated to the activation of a specific FC state (e.g. dashed arrows). Recurrent activations of FC state #1 (red time-course) are highlighted with (*) in the FCD matrix. (B) The structural connectivity matrix (SC) averaged over all subjects is compared with the mean FCC matrices of each state by calculating the cosine similarity between values in the upper triangular parts of the matrices.
