EEG records the electric action of neuronal groups,provides the study on the characteristic of brain information processing with important information.In this paper,the non-linear characteristic parameter of EEG signal is proposed according to G-P arithmetic based on the idea of restructure of phase space.The rule of selecting three important parameters,non-graduation area,embedding dimension and delay,is discussed.EEG signals under different brain conditions are recorded and their correlation dimensions are calculated.The experiments show that the correlation dimension of EEG signal can distinguish the characteristic of brain condition effectively.The correlation dimension can be used as the non-linear parameter of brain information processing.
