Fig. 3: Properties of slow waves.
From: Predicting lapses of attention with sleep-like slow waves
a Average waveform of the slow waves detected over electrode Cz during the behavioural tasks (red, left; N = 26 participants). The average waveform of slow waves detected during sleep (blue, right), extracted from another dataset (see Supplementary Methods), is shown for comparison. Slow waves were aligned by their start, defined as the first zero-crossing before the negative peak (see “Methods”). b Scalp topographies of the density of slow waves (arbitrary units) detected in wakefulness (top) and sleep (bottom). c Scalp topographies of wake slow waves properties (first column: temporal density; second: peak-to-peak amplitude; third: downward slope (D-slope); fourth: upward slope (U-slope); see “Methods”) averaged across participants (N = 26). d Scalp topographies for slow-wave density (first column), amplitude (second), downward slope (D-slope, third) and upward slope (U-slope, fourth) for the different mental state (ON (task-focused), MW (mind wandering) and MB (mind blanking)).
