More specifically, the study found that sleep sort of changes the brain's cellular structure.
更確切的說，該研究發現睡眠在某種程度上改變了大腦的細胞結構。
When the mice were asleep or anesthetized, the researchers found that there was more space between their brain cells,
當老鼠處于睡眠狀態或被麻醉時，研究人員發現，他們大腦細胞之間的空間增大了，
allowing a sort of brain plumbing apparatus called the glymphatic system to open wide and allow fluid to flow quickly through the brain.
使被稱為腦部類淋巴系統的類似排污管道的器官大大的打開，這樣腦脊液就能在大腦中快速的流動。
Other studies have shown that toxic molecules build up in the space between brain cells.
其他的研究表明，有毒分子在腦細胞的間隙中生成。
Researchers at the University of Rochester found that those molecules vanished faster from the brain when the mice were asleep.
羅切斯特大學的研究人員發現，這些分子在老鼠睡覺時從大腦中消失得更快。
So what does this mean?
所以，這意味著什么呢?
Well, it could give scientists new ways to study and potentially treat brain disorders like Alzheimer's by targeting the glymphatic system and helping it better flush away brain toxins.
這意味著通過針對腦部類淋巴系統可以幫助大腦更好的排除腦部毒素，使科學家們有新的方法研究并很有可能治好像老年癡呆癥這樣的大腦疾病。
