DEVELOPMENT OF EEG BIOFEEDBACK SYSTEM AND RE-SEARCH OF THE EEG BIOFEEDBACK IN THE ALPHA FRE-QUENCY BAND

In this paper, the EEG biofeedback system developed by the authors is described. The system is a microcomputer-based system, which could handle, amplify, record, exhibite, processe and transform the original EEG signals and control the feedback information. The system may be used to investigate the EEG biofeedback training conveniently in different frequency bands. The alpha component biofeedback training in normal human EEG done by the authors is reported in details. The authors also discuss the experiment program and result anlysis which show the feasibility of the method of the EEG biofeedback to increase alpha component. An explotory discussion of the difficulties in EEG alpha component biofeedback research and the effective solution is presented.
