脑机接口是神经组织与外部计算系统之间的直接通信途径，它绕过传统的神经肌肉输出通道，将记录的大脑活动实时转化为设备指令、合成语音或恢复的感觉反馈。
The field divides along an invasiveness axis: non-invasive modalities — scalp EEG, functional near-infrared spectroscopy — offer signal acquisition without surgical risk but at severely limited spatial resolution and signal-to-noise ratio; electrocorticography grids placed on the cortical surface occupy a middle tier; and fully intracortical approaches, typified by the Utah array and Neuralink’s flexible thread electrode system, record single-unit spikes from hundreds to thousands of neurons simultaneously at the cost of surgical implantation, foreign body response, and long-term electrode stability degradation.
信号处理流程——包括脉冲排序、局部场电位分解以及基于神经元群体动力学训练的深度学习解码器——将原始电生理信号转化为高维控制信号。其中，运动皮层解码用于光标控制和机器人肢体驱动，语音区解码用于想象或尝试语音合成，代表了临床上最先进的两个应用方向。结合神经记录和精确定时皮层或外周神经刺激的闭环架构，正在同时推进中风康复、难治性抑郁症和癫痫的治疗。
