Exponential decay function adjusted on relative SWA in NREM sleep for all-night EEG in the Fz derivation. Exponential decay fits: SWAt = SWA∞ + SWA0* e−rt. Solid line, morning types; dashed line, evening types. In morning types, regression was computed on 65 cycles (open triangels) and goodness of fit coefficient (R2) was 0.76. In evening types, regression was computed on 63 cycles (grey diamonds) and R2 was 0.82.
