Fig. 4: Results of the analyses on the relationship between theta and alpha band activity of N = 79 subjects.

a Temporal distribution of the difference peaks in theta band activity (red) and alpha band activity (blue). Figure parts b and b show the results of the classification theta band activity to alpha band activity. The MVPA was run with a TBA training set and an ABA test set. b Results of the temporal MVPA. The upper plot shows the AUC curve over time (with the shaded area showing the standard deviation) while the lower plot shows the temporal generalization. c Clusters of best performance in the top 2% of the AUC values of all significant voxels as identified by the DBSCAN algorithm.
