Supplementary Figure 5: Grand Average EEG Power vs. Frequency

From: Induction of self awareness in dreams through frontal low current stimulation of gamma activity

Supplementary Figure 5

Grand average FFT power was computed as a function of the EEG frequency (resolution = 1 Hz) for indicated stimulation conditions: sham (N = 30), 2 Hz (N = 31), 6 Hz (N = 19), 12 Hz (N = 18), 25 Hz (N = 26), 40 Hz (N = 44), 70 Hz (N = 21), and 100 Hz (N = 18). Averaging took place over frontal and temporal electrode sites (Fp1, Fp2, Fpz, F3, F4, Fz, F7, F8, T3, T4, T5, and T6), over stimulation sequences, and over subjects. The dips in power mark those frequencies for which a notch filter was applied. Phases I & II correspond to REM sleep, phase IV to wakefulness.
