  1. Abbreviations: M mean, SD standard deviation. ***p < .001, **p < .01, *p < .05. Power (log(μV2)) is averaged over all EEG electrodes unless otherwise specified. Note: the degrees of freedom for resting state (1,28) and task-specific (1,27) analyses are different due to the different number of participants included in each analysis
