Quantification of Effective Connectivity in the Brain Using a Measure of Directed Information

Figure 6

Application of directed information and Granger causality to EEG data. (a) Pairwise directed information. (b) Electrode pairs with significant DI values. (c) Pairwise Granger causality. (d) Electrode pairs with significant GC values. For (b) and (d), green dots indicate the location of the particular node, and white regions correspond to significant information flow from that particular electrode to other electrodes.
