In probable theory and informational theory, the mutual information of two random variables is quantity that measures the mutual dependence of the two random variables.The most common unit of measurement of mutual information is the bit, when logarithms to the base 2 are used.The brain is a complex system of collaborative work, and the brain information transfer need to be completed by numerous neuronal group collaboration.Analysis of synchronous relationship between multi-channel EEG signal can be obtained from different areas of the brain, informational integration, transmission and processing of the important information.Two channel synchronous analysis method is mainly used for analysis of the relationship between the two channel EEG signal, which can be divided into linear and nonlinear methods, and linear methods including correlation and consistency based on spectrum.The brain has obvious non-linear characteristic and dual channel, which are based on the nonlinear analysis of rapid development of synchronous method, for example, phase synchronization, nonlinear independence, mutual information and nonlinear correlation.The research content of this paper mainly is the extraction of EEG signals of normal and fatigue state, the EEG data denoising, filtering after pretreatment, combined with information entropy between information entropy is calculated for each channel EEG signals and any two channels of EEG signals, which can be get the mutual information matrix of each channel EEG the correlation analysis, the degree of signal of each channel height, and each channel under the change of EEG correlation and comparison of two state.The specific use of the MATLAB programming language is to achieve, and the results are analyzed in order to obtain the brain fatigue effects on brain network.By designing and running the program, the method of designing is verified.
