Figure 5
Comparisons in the net Causal Flow of Information (CFI), between post-NS (SC) and pre-NS (SC) are presented for each of the six hubs in panel A. First column refers to delta and second column to theta band. Comparisons related to the NS session are presented in the first row, and those related to the SC session in the second. A positive value of the net Causal Flow of Information corresponds to a prevalence of the outcoming flow with respect to the incoming flow. In Panel B comparisons related the normalized CFI between post-NS and post-SC sessions for each of the selected hubs are presented. In each graph and for each hub, the difference between post- and pre- or between post-NS and post-SC is presented: the bar represents the mean difference between the two periods’ values and the error-bar the mean ± standard error range. Gray asterisks denote a tendency towards significance (p < 0.1) whereas black ones’ significance at p < 0.05.
