要将基于运动想象的 BCI 应用于受试者，运动想象引起的 SMR（感觉运动节律）分量的信噪比和动态范围应该足够高。在这项研究中，进行了神经反馈训练实验，将四肢运动想象任务期间μ带上SMR的EEG带功率视觉反馈给受试者，以增强运动想象引起的振荡脑电图的ERD（事件相关去同步化）。通过头皮空间分布的变化和各通道脑电波功率响应来评价神经反馈训练的效果。结果表明，神经反馈训练增强了五名受试者中两名受试者的信噪比和 μ 波段 ERD 空间分布的定位。
To apply motor imagery-based BCI to subject, S/N and dynamic range of the SMR (sensory-motor rhythm) components elicited by motor imagery should be enough high. In this study, neuro-feedback training experiments, on which the EEG band power of SMR on μ-band during motor imagery task of limbs was visually fed back to subjects, were executed in order to enhance ERD (event-related desynchronization) of oscillatory EEG elicited by motor imagery. The effect of neuro-feedback training was evaluated by the change of spatial distribution on scalp and EEG band power response of each channel. It was shown that the neuro-feedback training enhanced S/N and localization of spatial distribution of ERD on μ-band in two of five subjects.
