Our sense of smell can have a large impact on how we think and feel.
我們的嗅覺對我們的思維和感覺能夠產生很大影響。
But did you know that mood can affect how we smell?
但你知道嗎，心情也是能夠影響嗅覺的。
According to a study by researchers at the University of Wisconsin Madison, feeling anxious can make typically neutral smells seem repugnant.
根據威斯康星麥迪遜大學研究人員的一份報告顯示，焦慮的心情能夠讓典型的中性氣味變得刺鼻。
The study involved a dozen volunteers who rated a panel of neutral smells.
該項研究邀請了12名志愿者并讓他們辨別一組中性氣味。
Then, while inside an MRI machine, subjects were made to feel anxious with disturbing images of car crashes and grisly war scenes.
然后通過向他們播放撞車和可怕的戰爭場景圖像來使他們產生焦慮的情緒，并用核磁共振儀進行觀察。
They were then once again asked to rank the panels of neutral smells.
接著，志愿者們被要求再次對這組中性氣味進行辨別。
But now, after having been made anxious by the images, they described some of the smells as negative. So, what's going on?
但是由于之前看到的影片產生了焦慮感，他們這次則表示聞到的氣體是刺鼻的。那會發生什么呢？
MRI revealed that during induced anxiety, the smell related circuits of the brain became intertwined with the brain's emotional circuitry.
核磁共振結果顯示，由于心情焦慮，大腦中跟嗅覺有關的回路跟情緒相關的回路產生了交織。
