Wavelet entropy in event-related potentials: a new method shows ordering of EEG oscillations

BIOLOGICAL CYBERNETICS 2001; 84(4)R. Quian QuirogaO. A. RossoE. Başar and M. Schürmann

a measure of entropy defined from the wavelet transform, namely the wavelet entropy (WS), to the study of event-related potentials (ERPs). WS was computed for ERPs recorded from nine healthy subjects with three different types of stimuli, among them target stimuli in a cognitive task. A significant decrease of entropy was correlated with the responses to target stimuli (P300), thus showing that these responses correspond to a more “ordered” state than the spontaneous EEG. Furthermore, we propose the WS as a quantitative measure for such transitions between EEG (“disordered state”) and ERP (“ordered state”).
