REM (rapid eye movement)

1.

1. The second type of sleep, known as REM-sleep(rapid-eye-movement sleep)occurs cyclically during the sleep period with rapid eye movements and frequent dream reports.
第二种睡眠，通常称为REM睡眠。它在睡眠时周期性出现。这时，双眼急促移动，并不时醒来说做了梦。

2. Rapid eye movement sleep consists of a dreaming state in which there is activation of the cortical and hippocampal electroencephalogram, rapid eye movements, and loss of muscle tone. Although REM sleep was discovered more than 50 years ago, the neuronal circuits responsible for switching between REM and non-REM sleep remain poorly understood. Here we propose a brainstem flip-flop switch, consisting of mutually inhibitory REM-off and REM-on areas in the mesopontine tegmentum. Each side contains GABA (gamma-aminobutyric acid)-ergic neurons that heavily innervate the other.
快动眼睡眠是一个包括有皮层和海马脑电活动的睡梦状态，可见眼球的快速运动和肌张力减低，尽管快动眼睡眠已经被发现50余年了，对其与非快动眼睡眠之间的神经回路却知之甚少，我们用脑干触发转换器，包括脑桥背盖区一个互相抑制的快动眼-关、快动眼-开区域，每侧均包含高度互相支配gamma氨基丁酸能神经元。

3. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep.
这一时期的眼球快速转动会持续8到15分钟称为REM 睡眠。

4. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM slee p.

7. This was curious, because during so-called REM sleep (rapid eye movement), our muscles are usually paralysed.
这在当时是很新奇的，因为在所谓的REM（Rapideyemovement快速眼球运动）睡眠中，我们的肌肉通常是处于麻痹状态的。

8. Rapid eye movement Both the REM sleep and the brain waves happen at the same time.

11. You've probably heard that dreams only occur during rapid eye movement or REM sleep.
也许你听说过只有在眼球高速运动或者快速眼动睡眠时才会做梦。

12. We also know that at seven months a fetus is dreaming, its muscles and eye movements giving the tell-tale signs of REM (or rapid eye movement) sleep and non-REM sleep.
我们还知道7个月大小的胎儿也做梦，胎儿的肌肉和眼动能清清楚楚地反映出快速眼动睡眠（REM）和非快速眼动睡眠（non-REM）信号。

13.

13. Then REM sleep emerges, rapid eye movement sleep.
这时就进入REM快速眼动睡眠。

14. And cognitive neuroscientists have discovered that dreams and the rapid eye movement (REM) that happens while you're dreaming are linked to our ability to learn and remember.
认识神经学家已经发现，梦和你入梦时的快速眼动（REM），与我们的学习、记忆能力是相联系的。

15. There are two kinds of sleep, Rapid Eye Movement (REM) sleep and Non-REM (NREM) sleep.
睡眠有两种形式，分别是快速眼动（REM）睡眠和非快速眼动（NREM）睡眠。

16. Some researchers theorize that the REM, or rapid eye movement, phase of sleep is when the brain produces and consolidates neural networks for memory and cognition.
一些研究人员提出，大脑在快速动眼睡眠期会产生并巩固形成记忆和认知的神经元。

17.

17. The results of the study add to the growing body of evidence that Rapid Eye Movement (REM) sleep is crucial to the brain's ability to lay down and consolidate memories.
此前有证据表明，眼动睡眠对大脑记忆的能力至关，而结果印证了该说法。

18.

18. The two researchers called this Rapid Eye Movement or REM sleep. One nighttime physical activity that may actually help sleep is sex, which can have a sedating effect.
两位研究员称这种睡眠阶段为快速眼动睡眠。性生活可能是一种对睡眠的实际帮助的晚间身体运动。

19. However, it reduces their rapid eye movement (REM) sleep, the only phase during the sleep cycle when the body recovers and prepares itself for the waking part of the day.
然而，它会减少你的快速眼动睡眠（REM），这是唯一能让身体充分恢复、为清醒地早晨做好准备的睡眠模式。
