摘要
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。
Electroencephalogram (EEG) signals are the electrical activities in the cortex or on the surface of scalp caused by the physiological activities of the brain which play a key role in the diagnosis of brain and the functional determination of brain. The authors reviewed the history and current situation of EEG research and discuss specially on the using of chaos, ANN, wavelet transform, wigner distribution etc.in EEG signals processing. Finally, the prospect of EEG research was described.
