脑电信号是脑神经细胞电生理活动在大脑皮层或头皮表面的总体反映 ,脑电信号的研究

一直是生物医学领域难度很大且倍受人们关注的课题。在简要回顾了脑电研究的历史和现状的基础上 ,重点论述了混沌分析法、人工神经网络(ANN)分析法、小波变换法、Wigner 分布等在脑电信号分析和处理中的应用情况。最后展望了脑电信号研究的发展应用前景。-EEG is a brain cell electrophysiological activity in the cerebral cortex or the scalp surface, the overall reflection of the study EEG bio-medical field has always been a very difficult and oft-topic of concern. After a brief review of the history and current status of EEG research, based on the analysis focuses on the chaos, artificial neural network (ANN) analysis, wavelet transform, Wigner distribution in the brain signal analysis and processing of the application. Finally, the future research and development of EEG application.
