Is bedtime just a time for dreaming? Do our brains turn off for the night? What if I told you that scientists
recently discovered that our brains may be just as busy at night as they are during the day? 37 Researchers
at the University of Rochester found that the brain may be busy cleaning house -- cleaning out harmful waste
materials.
As with many studies, the researchers turned to mice for help. They studied mice that had colored dye
injected into their brains. They observed the mice brains as they slept and when they were awake. The researchers
say they saw that the brains of sleeping mice were hard at work. Dr. Maiken Nedergaard led the study. 38 It
seems they have daytime jobs. Later they “moonlight” at a nighttime job. “Moonlighting” is working a nighttime
job in addition to a day job. And this study says that is what our brains seem to be doing – working an extra job at
night without additional pay for overtime. Whereas during sleep, they work very, very hard at removing all the
waste that builds up when we are awake.
“When we are awake, the brain cells are working very hard at processing all the information about our
surroundings. The researchers say that the waste material includes poisons, or toxins, responsible for brain
disorders such as Alzheimer’s disease. It is not just beauty sleep. The brain needs us to sleep so it can get to
work. 39 This shrinking permits waste to be removed more effectively.
Dr. Nedergaard says these toxins end up in the liver. There, they are broken down and then removed from the
body. “So our study suggests that we need to sleep because we have a macroscopic cleaning system that removes
many of the toxic waste products from the brain.”
The brain’s cleaning system could only be studied with new imaging technologies. The test animal must be
alive in order that this brain process may be seen as it happens. Dr. Nedergaard says the next step is to look for the
process in human brains. 40 The research may also one day lead to treatments to prevent or help fight
neurological disorders.

This shrinking permits waste to be removed more effectively.
- A They also found that during sleep, the brain’s cells shrink, or become smaller.
- B While we sleep, our brains are doing much more than getting ready for the next day.
- C She said the results demonstrate just how important sleep is to health and fighting disease.
- D The brain expert says our brains perform two very different jobs.

請仔細觀察空格後面的那句話，它開頭使用了『This shrinking（這種萎縮現象）』。按照英文的寫作邏輯，如果作者用『這種』來描述一個現象，那麼在空格的句子裡，應該會先出現哪一種動作或特徵，才能讓後面的讀者明白『這種』指的是什麼呢？
