The Study of C0 Complexity on Epileptic Absence Seizure

摘要

Absence seizure is one of the most common types of epileptic seizure; it is characterized by a short duration,an abrupt start and termination with high frequency and complex dynamic transition.Complexity can reflect the regulation level of dynamical system.This paper employ C0 complexity,which can well describe and quantify non-linear and nonstable biomedical signals,to calculate and analyze dynamic changes of complexity for EEG signals during the process of epileptic absence seizure.Meanwhile,it also study the dynamical changes of complexity for both original EEG signals and filtered EEG signals as well as the different influence of improved C0 complexity algorithm on the outcome.
