During the process of epileptic seizure,there are two states of the epileptic brain: the interictal state,steady-state electroencephalography(EEG) ongoing activity,and the ictal state,which is characterized by paroxysmal occurrence of synchronous oscillations.Different dynamic phase spaces and chaotic attractors are found during the process.By using methods of False Nearest Neighbors,mutual information and C-C method,phase space is reconstructed and parameters of chaotic attractor are computed and some new viewpoints on this foundation are put forward.
