Normally, those circuits don't interact much, but when the subjects were anxious, the circuits morphed into something like a unified network, essentially rewiring the brain.
正常情况下，这些回路并不会发生太多的互动，但是当人体变得焦虑时，这两种回路就会变成一个看似交织在一起的网络，本质上来说就是对大脑的回路进行了重组。
And somehow, that rewiring affected how the subjects interacted with the world through smell.
而且，不知何故，这种改变影响了志愿者通过嗅觉与外界进行联系的方式。
So why does this matter?
为什么知道这一点会很重要呢?
First, because it helps explain how anxiety can feed on itself.
首先，它可以有助于解释焦虑是如何变强的。
In so far as being anxious makes things smell generally worse, those worse smells may in turn cause greater anxiety, creating an anxiety feedback loop.
如果说一定程度的焦虑会让人感觉闻到的东西很刺鼻，那么越刺鼻的气味则会反过来引发更强烈的焦虑感，由此便产生了一种焦虑的恶性循环。
But understanding how emotion and smell can intert wine may also lead to ways to use smell as a way to combat anxiety and other mental disorders an intriguing possibility that maybe borne out with more research.
好的一面是，如果理解了情绪跟气味是如何互动的原理，我们可以利用气味来战胜焦虑和其他的心理疾病，但是这种有趣的可能性还需要投入更多的研究来加以证实。
