And so it turns out that there is a nerve that's right here that runs up here that innervates these three fingers, and it's close enough to the skin that we might be able to stimulate that so that what we can do is copy your brain signals going out to your hand and inject it into your hand, so that your hand will move when your brain tells your hand to move.
实际上这里有一根神经 一路上来并支配这三根手指的活动， 而这根神经又离皮肤足够近， 让我们能够 刺激它，所以我们能做的 是复制从你的大脑 向手臂发出的信号, 并把这个信号注入到你手臂里， 于是你的手臂会在 你的大脑告诉手臂要动的时候动。
