| Abstract: | This paper reports a method of chaos and fractal for a study of the auditory evoked potential of the brain stem. The results of one-dimensional time-amplitude, frequency-amplitude and phase-space curve reconstructed in time series were obtained from the scalp electrodes in different brain states. Algorithms of correlation dimension are used to obtain the fractal dimension of the time serial in different states before, during and after the exercise. The result shows that the dimension during exercise is lower than those before and after The phase-space curves are used to analyze the obvious different conditions in different brain states. The principle of the study of the EEG signal with chaos theory consists in that the human body is taken as a nonlinear dynamic system and the variables of the system can be described by fractal dimension. |
