摘要
Based on the clinical epileptic electroencephalography (EEG) data, the time courses of the largest Lyapunov exponent (LLX) are investigated for different states (i.e. interictal, preictal, ictal and postictal) of seizures induced from different background. Two seizure response models are proposed. (1) for seizures occurring in sleep or wake state, it seems that the brain is disturbed by a random signal, so that the subsystems of the brain will need a complex interaction to get into a highly synchronous rhythm. (2) for seizures induced by flash stimulation, it likes that the brain is interfered by a strongly high frequency signal, so that the subsystems of the brain will be driven directly into a similar oscillation.
