Abstract

Complex partial seizures belong to the most common type of epileptic seizures. The main purpose of the case study is the application of the Van der Pol model oscillator to study brain activity during temporal left lobe seizures. The oscillator is characterized by three pairs of parameters: linear and two nonlinear, cubic and Van der Pol damping. The optimization based on the normalized power spectra of model output and real EEG signal is performed using a genetic algorithm. The results suggest that the estimated parameter values change during the course of the seizure, according to changes in brain waves generation. In the article, based on values of sensitivity factor of parameters, and, sample entropy non-stationary of considered seizure phases are analyzed. The onset of the seizure and the tangled stage belongs to strongly non-stationary processes.
