Moving from muscles to the mind, brain-computer interface technologies have advanced significantly in recent years, giving rise to “neuro-prosthetics,” which has already enabled paraplegics to navigate a computer mouse with their thoughts and monkeys to operate a giant robotic arm. Scientists are now working to pinpoint the neuro-chemistry of thought and emotions so accurately that new technologies could be developed to allow humans to communicate them silently.
脑机接口技术近年来从肌肉到头脑取得了显著的进展，进而引出了既能让截瘫患者用意念操控鼠标、也能让猴子操作巨型机械臂的“神经假肢”系统。科学家们现在正全力确定人类思想和感情的神经化学变化，以便研发出不借助语言即可沟通思想的全新技术。
