- Figure 1.
Power spectra for each subject in each of the conditions. Each panel represents data from one subject averaged across electrodes. Points represent the peak frequency for each condition. The grand mean across subjects is shown on the right. Shaded regions represent the within-subject SE (Cousineau, 2005; Morey, 2008).
- Figure 2.
Distribution of α peak frequency across the scalp. A, α peak frequency in each resting state condition. B, α peak frequency averaged across resting state conditions.
- Figure 3.
Mean α peak frequency across resting state conditions. Colored points and lines indicate data from individual subjects. The bold black line represents the mean averaged across subjects; **p < 0.01.
- Figure 4.
Distribution of normalized α power across the scalp. Power is plotted as percentage change from the mean across all resting state conditions, electrodes, and subjects to better illustrate the differences in power occurring across different resting state conditions. Power values that deviate strongly from the grand mean will be non-zero in the averaged data. A, Normalized α power in each resting state condition. B, Normalized α power averaged across resting state conditions.
- Figure 5.
Mean normalized α power across resting state conditions. Colored points and lines indicate data from individual subjects; the same colors represent the same subjects as Figure 3. The bold black line represents the mean averaged across subjects; *p < 0.05, **p < 0.01.
