From: Alpha Power Predicts Persistence of Bistable Perception
Distribution of alpha power after normal sleep in the frequency-, space-, and time-domain. (a) Power spectrum of the EEG recorded over parietal and occipital electrodes in the interval between the button presses indicating reversals. The power spectrum shows a clear peak at 9 Hz, the gray area indicates the frequency boundaries used in the subsequent analysis (7–11 Hz). (b) Topographic distribution of alpha power during periods of perceptual stability. For each stable period, alpha power was averaged over the parietal and occipital electrodes (indicated by a marker). The value was used as regressor to predict the perceptual duration of the present percept.
