Generalized Information Equilibrium Approaches to EEG Sleep Stage Discrimination

Figure 2

Lomb-Scargle periodogram power for value PDF estimations. Lines represent mean data for EEG of subjects from waking (black) and sleep stage 2 (blue) and subjects from sleep stage 3 (green), each with eight different one-minute segments. Data was analyzed for values and the PDF estimated and then normalized Lomb-Scargle periodogram area with a threshold of calculated. (a) = 0.004 sec; (b) = 0.04 sec; (c) = 0.4 sec; (d) = 4 sec. by repeated-measures ANOVA for Lomb-Scargle periodogram area difference between waking and sleep stage 2 (a) and waking and sleep stage 3 (a–d); between waking and sleep stage 2 (b).
