    一句问候常常伴随挥手,一声肯定也可能配合点头。对于语言和肢体活动受损的人,恢复交流不只是把话表达出来,还包括这些非语言动作。美国加州大学旧金山分校Edward Chang团队利用单个脑表面植入阵列,同时解码语言与手势尝试。2026年9月14日,相关研究发表于《Nature Neuroscience》。
    脑机接口旨在将脑活动转化为操控外部设备的指令,从而恢复丧失的功能。以往脑机接口研究多将说话、移动光标或做手势分别处理。然而,言语和上肢/头面运动在感觉运动皮层部分重叠,单独训练“只说话”或“只动手”的解码器并行时可能互相串扰。
    此次,研究团队使用置于感觉运动皮层上方的脑植入装置,记录了3名声道和肢体瘫痪参与者的神经活动。他们首先证明,单个植入装置能采集与多种运动类型相关的信号,包括上肢运动和与言语相关的嘴部及面部运动,如耸肩、握拳挥动或点头;随后,团队在其中2名参与者中使用并行的言语和手势解码器,驱动一个全身虚拟形象,参与者被要求尝试做出特定手势、回应对话提示,或同时完成两者。
    在对话任务中,该系统准确解码了2名参与者的言语和手势:其中一名参与者在3个对话任务区块中,言语和手势解码的中位准确度均达到100%。
    研究团队发现,同时使用言语和手势数据训练系统可提高性能并减少错误。他们指出,这项技术在投入应用之前,还需纳入更多参与者,并使用规模更大的词汇集和手势集进行测试。
