949-双手脑机接口打字神经假体

这项研究介绍了一种创新型脑机接口（iBCI），旨在通过解码双手手指运动意图来恢复瘫痪患者的沟通能力。研究团队开发了一种模拟QWERTY键盘布局的神经假体，使两名患有四肢瘫痪（分别由ALS和脊髓损伤引起）的临床受试者能够通过想象指尖敲击进行盲打。实验结果显示，该系统在仅需少量校准的情况下，实现了最高每分钟110个字符（约22个单词）的输入速度，并保持了极高的准确率。这种方法利用受试者对键盘布局的肌肉记忆，比传统的“点选”式接口更快速且直观。研究证明，即便在严重的语言和肢体功能障碍下，大脑皮层仍保留着精细的双手运动表征。该技术不仅突破了现有手部运动解码的速率极限，也为改善重度瘫痪者的生活质量提供了高效、隐私的数字化交互手段。References:* Jude J J, Levi-Aharoni H, Acosta A J, et al.
