项目摘要

EEG amplifiers (FM515s, ss) picked up the EEG at Fp_2 position, and divided it into six bandpass waves (the θ_2, α_1, α_2, α_3, β_2 waves and the artifact). It distinguished one dominant wave in the EEG in each 2 second interval. The speed of A/D conversion is 20ms. The amplitude of these six bandpass waves is an out put with a 1/256 resolution of the full scale every 2 seconds. Signal sounds at the BFT by means of the image based on autogenic training, color, scene and sound were sent from FM515S when the Fp_2 α_2 wave appeared predominantly. Performance was measured by means of concentration level meter and others.The following several researches were performed in series :1 Examination of the increasing concentration by the EEG α_2 wave biofeedback training using the autogenic training method.2 Relationship between the improvement of performance and prevalent Fp_2 α_2 wave by EEG biofeedback training using the imagination.3 Relationship between a person's comfortable feelings caused by sound and the prevalent EEG.4 Relationship between the performance of hitting the mark in kyudo and the control of heart rate by biofeedback training using autogenic training with Kyudo athletes and others.As a result, the following conclusions were obtained :1. A high level of concentration to one point is accompanied by a large time fraction of the Fp_2α_2 wave.2. Intensification of the Fp_2α_2 wave can be accomplished by BFT of the prevalent EEG α_2 wave using the autogenetic training method.3. The concentration level to one point can be increased by the intensification of the Fp_2 α_2 wave accomplished through BFT using the autogenetic training method.4. The time fraction of each wave prevalent in EEG is a reasonable measure of psychological response more than the time average of EEG amplitude.5. The concentration level to one point can be increased by the intensification of the Fp_2 α_2 wave accomplished through BFT using the imagination.And others.

脑电放大器（FM 515 s，ss）在Fp_2位置拾取脑电，并将其分成6个带通波（θ_2，α_1，α_2，α_3，β_2波和伪影）。它在每2秒间隔内区分EEG中的一个主导波。A/D转换速度为20 ms。这六个带通波的振幅是每2秒以满量程的1/256分辨率输出的。当Fp_2 α_2波占优势时，FM 515 S通过自生训练的图像、色彩、场景和声音在BFT发出信号声。通过浓度水平计等测量性能，进行了以下几项系列研究：1利用自生训练法进行脑电α_2波生物反馈训练，对提高注意力的作用进行了考察。2利用自生训练法进行脑电生物反馈训练，提高运动成绩与Fp_2 α_2波的流行之间的关系。3由声音引起的人的舒适感与流行脑电的关系。4利用自生训练法对柔道运动员等进行脑电生物反馈训练，对柔道运动员的击球成绩与心率控制之间的关系进行了研究。结果表明：得出以下结论：1.一个高浓度的点伴随着一个大的时间分数的Fp_2α_2波. Fp_2α_2波的强化可以通过自体训练法对流行EEG α_2波进行BFT来完成.采用自体训练法，通过强化BFT完成的Fp_2 α_2波，可使浓度水平提高到一个点. EEG中各波的时间分数比EEG振幅的时间平均值更能合理地衡量心理反应.用想象力通过BFT完成Fp_2 α_2波的强化，可将浓度水平提高到一个点。
