You know, we are animals with a prefrontal cortex.

要知道，我们是有前额叶皮层的动物。

So even if someone with CCB was born with a thinner auditory cortex or was at risk of developing one, having to rely on their hearing could have strengthened that brain region.

因此，即使患有 CCB 的人出生时听觉皮层就较薄，或有发育听觉皮层的风险，但必须依赖他们的听觉，可能会增强的那个区域。

And while breathing does have a voluntary control through the brain's motor cortex, where we can stop and start at will, there's also an involuntary control through the brainstem that keeps us breathing when we're unconscious.

虽然呼吸确实有通过动皮层的自愿控制，我们可以随意停止和开始， 但也有通过干的非自愿控制， 让我们在失去知觉时保持呼吸。
