Topographical maps of the parameters of Process S. (A) Parameters estimated for average normalized data (see Methods for details of normalization). (B) Average of the parameters derived for each participant separately. Maps of individuals are illustrated in Figure 2. Left to right: Increasing time constant τ
, decreasing time constant τ
, distance between upper and lower asymptote (UA-LA), mean SWA in NREM sleep (stages 2-4) of the first 7 h 27 min of baseline sleep (SWA
), and goodness of fit R2. Each map was scaled separately between minimal and maximal values. At the top right of the maps, maxima (max) and minima (min) of the maps are indicated.
