Abstract:
This paper applies the method of fast Fourier transform based on the Gabor transform for the simultaneous treatment in the time-frequency space of electroencephalographic (EEG) signals. This method can be used to analyze the time evolution of the traditional frequency rhythm of an EEG signal and can visualize the frequency-band behavior during epileptic seizure. The linear correlation between the obtained frequency evolution series can be used to obtain information about the interaction and, consequently, the causality between EFG signals from different regions of the brain and the frequency bands in other regions. The systematic calculation of these correlation can be a valuable tool for the identification of the epileptic focus, as well as for the study of seizure dynamics.
