Studying the brains of sleeping mice, the researchers found that neurons drive cleaning efforts by firing electrical signals in a coordinated fashion to generate rhythmic waves in the brain, Jiang-Xie explained. They determined that such waves propel the fluid movement. The research team ...
1Sleep and DreamsThe brain is very active when a person is sleeping. Scientists know that there are five stage(阶段)of sleep. Stage 1 starts after you fall asleep. If there is a noise or a bright light, you wake up very easily. In stage2: your brain waves(脑电波)are very slow.Stag...
The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!以及最后段“. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. ”可知...
that are very different from our waking life brain waves. These long-burst brain waves are called delta waves. 和醒着时的脑波很不一样。這些長的脈衝 被稱為 δ(delta)波。 When we don't get the deep sleep we need, it inhibits our ability to learn 当我们没有得到我们需要的深睡时, 就会...
You can't see your sleeping pet's brain waves, but its behavior can tell you when the cat might be dreaming. If you watch closely, you will see that as your cat falls asleep, her breathing becomes slow and her body still. She has entered the first stage of sleep, called slow-wave ...
根据文章内容,结合第一段中“You can't see your sleeping pet's brain waves, but its behavior can tell you when Fido or Fluffy might be dreaming.(你看不见睡着的宠物的脑电波,但是它的行为可以告诉你宠物什么时候在做梦。)”可知,本文主要讲述动物睡眠的行为表明动物也会做梦,并解释了动物的梦的内容。
根据第一段“You can't see your sleeping pet's brain waves, but its behavior can tell you when Fido or Fluffy (possibly your cat's name) might be dreaming. If you watch closely, you'll see as your cat falls asleep, her breathing becomes slow and regular and her body still. She has...
Its paws and whiskers (胡须) move and it shakes an ear. Now it has entered the quick-wave sleep. Generally speaking, fast eyeball movement' and 'fast brain waves' can be considered as the symbols of dreaming.”即可得出答案B。结果一 题目 【题目】DYou can't see your sleeping pet's ...
You can't see your sleeping pets brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you'll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slow-...
