脑机接口（BCI）通过记录并解码中枢神经系统的活动信号，并将其转化为可执行的指令，用以控制外部软件或硬件，从而实现大脑与外部世界的交互、通信与控制。本研究基于MetaBCI软件平台和稳态视觉诱发电位范式，建立了多分类任务与穴位电刺激之间的映射关系，从而实现了脑电编码和穴位刺激之间的闭环，构建了真正意义上的针灸BCI平台，实现了脑控下的针灸刺激强度调节及脑控下的治疗穴位选择。该平台是针灸和BCI融合的方法学探索，对同类研究具有示范效应。

A brain-computer interface (BCI) records and decodes activity signals from the central nervous system, converts them into executable commands to control external software or hardware, and thereby realizes interaction, communication and control between the brain and the external world. Based on the MetaBCI software platform and the steady-state visual evoked potential paradigm, this study establishes a mapping relationship between multi-classification tasks and acupoint electrical stimulation. It thus forms a closed loop between electroencephalographic coding and acupoint stimulation, develops an authentic acupuncture BCI platform, and enables brain-controlled adjustment of acupuncture stimulation intensity as well as brain-controlled selection of therapeutic acupoints. This platform represents a methodological exploration integrating acupuncture therapy with BCI, and can serve as a model reference for similar research.
