比如你不小心碰到了热火炉，你皮肤中的神经就会向大脑发射疼痛信号，于是大脑就会发回信号让手挪开。
For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away.

正像她最近在维也纳举行的欧洲神经科学论坛上向听众解释的那样，如果她是对的，那么她或许已经打开了治疗其他形式的持续性疼痛的大门。
If she is right, as she explained to an audience at the recent Forum of European Neuroscience in Vienna, she may have opened a door to the treatment of other forms of persistent pain.
而是，它们积累所接收到的能量，只有当积累的能量达到一定临界极限时，它们才会向其他神经元发送自己的能量。
Instead, they sum their received energies, and they send their own quantities of energy to other neurons only when this sum has reached a certain critical threshold.
