scalp eeg
解釋
頭皮腦電圖-
Electroencephalogram ( eeg ) or brain wave is a typical kind of bioelectricity signals. eegs are brain electrical potentials recorded by electrodes placed on the scalp of subjects
腦電信號作為一種典型的生物電信號，由放置在頭皮的電極獲得並被記錄，其中包含了大量的腦內神經元活動信息。 -
Electroencephalogram ( eeg ) is a measurement of the time - varying potential differences between electrodes fixed on the scalp
腦電，即從頭皮表面記錄到的電波信號，反映了電極之間的電位差隨時間的變化。 -
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，還是在認知科學研究領域都是十分重要的。 -
Ica algorithm is used to the artifacts removing and patterns extraction of mental eeg signals from different mental tasks. the results show that ica can effectively detect, separate and remove a wide variety of artifacts from eeg recordings, such as eog, ecg by studying the eeg independent sources and their projections on human scalp, we can find that some steady independent components always appear when the subject repeats the same mental tasks
探討了ica用於思維腦電特徵提取的可行性：通過使用ica對進行不同心理作業的思維腦電進行分析處理，發現了與心理作業相對應的腦電獨立分量特徵，這些穩定的獨立分量特徵將可以為心理作業的分類和腦認知科學的研究提供新的實現方法。
