Brain-controlled interfaces are devices that capture brain transmissions involved in a subject's intention to act, with the potential to restore communication and movement to those who are immobilized. Current devices record electrical activity from the scalp, on the surface of the brain, and within the cerebral cortex. These signals are being translated to command signals driving prosthetic limbs and computer displays. Somatosensory feedback is being added to this control as generated behaviors become more complex. New technology to engineer the tissue-electrode interface, electrode design, and extraction algorithms to transform the recorded signal to movement will help translate exciting laboratory demonstrations to patient practice in the near future.
脑控接口是一种捕捉与受试者行动意图相关的大脑信号传输的设备，有望为那些行动不便的人恢复沟通和行动能力。目前的设备记录头皮、大脑表面和大脑皮层内的电活动。这些信号正被转化为驱动假肢和计算机显示器的指令信号。随着所产生的行为变得更加复杂，体感反馈也被添加到这种控制中。在不久的将来，用于设计组织-电极接口、电极设计以及将记录信号转化为动作的提取算法的新技术，将有助于把令人兴奋的实验室演示转化为患者实践。
