Fig. 4

Directed muscle networks obtained using non–negative matrix factorization of the PDC. 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-, the direction of connectivity by the arrow); and (C) detailed significance in the correlation matrix
