%X Grassberger Procaccia algorithm is used to calculate the correlation dimension of 8-channel human EEG signals. T'he influences of length of time series, time delay and embedding dimesion on the value of EEG correlation dimension were investigated. It indicated that the results of calculation are greatly influenced by the reasonable choice of parameters. Besides, it seemed that EEG signals can not be defined as a stable chaotic attractor. Therefore,the attempt to take the correlation dimension as a precise and objective parameter to indicate human brain functions in different physiological states is almost unfeasible.
