FIGURE 6.

Changes in connectivity between conditions and frequency components in the minimally-connected multiplex coherence network. (A) Frequency components 4–8, 8–22, and 22–60 Hz, obtained with non-negative matrix factorization. (B) Coherence networks in the 2:1, transition (T) and 1:1 mode of coordination (columns) and the frequency components (rows). Colors in the networks depict different modules and node size and edge width represent degree and connectivity strength between muscles, respectively. (C) Global efficiency, transitivity and average strength of the coherence networks per frequency component and condition. Error bars indicate standard errors of the mean and asterisks significant differences between conditions (α < 0.005).
