Abstract
A classic problem in physics is the analysis of highly nonstationary time series that typically exhibit long-range correlations. Here we tested the hypothesis that the scaling exponents of the dynamics of sleeping EEG have more stable pattern than those of waken EEG by analyzing its fluctuations. We calculated the modified fluctuations of EEG stage with detrended fluctuation analysis(DFA). DFA is very useful to detect a long-range correlation in the time-series. We found a scaling exponent of sleeping stage is larger than that of waken.
