Interregional SFP phase-locking during task performance for subject G2 (A), subject C3 (B), and subject A2 (C). Left: TFR maps show interregional phase-locking dynamics separately for correct, incorrect, and control task trials. The color scale denotes z scores of oscillatory power changes with respect to baseline. Right: TFR difference maps depict differences in phase-locking between correct and incorrect trials (CC vs. II) and between control task and WM trials (control vs. WM). In all maps, the color scale denotes z scores of oscillatory power changes with respect to baseline. Heavily colored, outlined regions of the maps indicate time–frequency clusters that significantly differ from baseline ( p < .001, cluster permutation distribution, 5000 iterations).
