A Review of Research on EEG Signal Preprocessing Methods

EEG signal is a complex and important biological signal, which is widely used in the research of brain-like intelligence technology and brain-computer interface. In this study, the types and characteristics of common non-physiological artifacts and physiological artifacts that interfere with normal EEG signals are introduced, and the causes of physiological artifacts are analyzed in detail. Through the review of various EEG artifact removal methods and the analysis of the application status, the research progress of traditional artifact removal methods and new artifact removal methods is compared and summarized, and the advantages and disadvantages of artifact removal methods are further analyzed. Some methods have been successfully applied to the processing of electrocardiogram, ECG and EMG artifacts in EEG signals.The current demand for artifact removal from EEG signals and the problems faced are also given in the present study, and the future research directions are analyzed and prospected.
