Figure 3

EEG profile for all-night VS/UWS recording with the lack of sleep spindles and poor SWA, but the presence of alpha, theta, beta waves- in a large proportion but continuous and not differentiated activity. 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.
