The regulation of the timing of sleep is thought to be linked to the temporal dynamics of slow‐wave activity [SWA, electroencephalogram (EEG) spectral power in the ∼0.75–4.5 Hz range] in the cortical non‐rapid eye movement (NREM) sleep EEG. In the two‐process model of sleep regulation, SWA was used as a direct indication of sleep debt, or Process S. Originally, estimation of the latter was performed in a gross way, by measuring average SWA across NREM–REM sleep cycles, fitting an exponential… Expand
