Presently , the brain science research shows that multi - channel eeg data collected from various scalp electrodes placed according to a certain criterion contains rich physiological phenomena and much more dynamic information . the work of eeg source segregation , identification , and localization are very important and difficult in brain science research and cognition science research 腦電( eeg )中蘊(yùn)涵著豐富的生理、心理及病理信息,腦電信號的分析及處理無論是在臨床上對一些腦疾病的診斷和治療,還是在認(rèn)知科學(xué)研究領(lǐng)域都是十分重要的。
