Spectral and phase correlation of EEG bursts ensemble: wavelet analysis
Sergey V. Bozhokin, И. Н. Суслова · 2016
The paper presents new algorithm to evaluate instantaneous correlation of nonstationary Electroencephalogram ( EEG ) signals related to different brain leads. The method includes calculation of instantaneous values of spectral integrals by Continuous Wavelet Transform ( CWT ). To adjust spectral and temporal resolution of the signals we introduce the adaptive Morlet mother wavelet function with a control parameter. To test the technique we composed mathematical models of EEG signals based on real EEG record and special short-time elementary signals. We discuss the application of the method in different fields of physics.
