Figure 4

EEG profile of 24 hours recording. An example of continuous monitoring of patient’s EEG activity during long period of time. Recording with many sleep spindles detected but no typically concentrated during night, not correlated with the slow waves and without variation across 24 hours. Subplots organized as in Figure 1. (a), (b), (c) and (e) – numbers of alpha, theta and beta waves and sleep spindles, detected per subsequent 3-min epochs, (d) markers of occurrence of K-complexes, (f) percentage of each 20-second epoch occupied by SWA; horizontal lines at 20% and 50% mark the classical criteria for stages 3 and 4 scoring.
