Now if you look at the brain of an individual who has a cochlear implant and you have them listen to speech, have them listen to rhythm and have them listen to melody, what you find is that the auditory cortex is the most active during speech.
我们来观察一下一位人工耳蜗使用者的大脑， 让他听人讲话， 或者听节奏，听旋律， 我们会发现他的听觉皮层 在他听别人讲话时最活跃。
