Fig. 3

Undirected muscle networks obtained using non–negative matrix factorization of IMCoh. The figure illustrates (A) the frequency spectrum of the four identified components (A–D); (B) the binarized networks obtained using proportional thresholding for the networks corresponding to the frequency components in panel A (the strength of connection is indicated by the width of the lines, continuous among muscles of anterior thigh and leg, dotted for the other muscles); and (C) detailed significance in the correlation matrix
