研讨职员发明,临时就寝缺乏会使大脑肃清少量神经元和突触衔接,并且规复就寝大概并不克不及彻底修复毁伤。

就寝与大脑.jpg
The need for sleep goes far beyond simply replenishing our energy levels every 12 hours. Our brains actually change states when we sleep to clear away the toxic byproducts of neural activity left behind during the day.

人们对就寝的需求不只仅是为了每12个小时增补一下膂力。实践上,我们睡觉的时分,大脑会改动形态,肃清白昼神经运动留下的有毒副产品。

Weirdly enough, the same process starts to occur in brains that are chronically sleep-deprived too - except it's kicked into hyperdrive.

奇异的是,临时就寝缺乏,大脑内也会停止如许的顺序,只是它会进入过分肃清形态。

Researchers have found that persistently poor sleep causes the brain to clear a significant amount of neurons and synaptic connections, and recovering sleep might not be able to reverse the damage.

研讨职员发明,临时就寝缺乏会使大脑肃清少量神经元和突触衔接,并且规复就寝大概并不克不及彻底修复毁伤。

A team led by neuroscientist Michele Bellesi from the Marche Polytechnic University in Italy examined the mammalian brain's response to poor sleeping habits, and found a bizarre similarity between the well-rested and sleepless mice.

意大利马尔理工大学神经迷信家米歇尔·贝蕾西率领的团队研讨了哺乳植物的大脑对就寝缺乏的反响,他们发明苏息工夫富足的小鼠与就寝缺乏的小鼠之间有乖僻的类似性。

Like the cells elsewhere in your body, the neurons in your brain are being constantly refreshed by two different types of glial cell - support cells that are often called the glue of the nervous system.

就像你身材其他部位的细胞一样,你大脑里的神经元也在不时被两种差别的神经胶质细胞所更新,这些支持细胞常常被称为神经零碎的粘合剂。

The microglial cells are responsible for clearing out old and worn out cells via a process called phagocytosis - meaning "to devour" in Greek.

这种微神经胶质细胞经过一个被称为吞噬景象(phagocytosis在希腊语中是“吞噬”的意思)的进程来肃清老细胞和衰竭的细胞。

The astrocytes' job is to prune unnecessary synapses (connections) in the brain to refresh and reshape its wiring.

星型胶质细胞的作用是肃清大脑中不用要的突触(衔接)来规复偏重塑它的神经网络。

We've known that this process occurs when we sleep to clear away the neurological wear and tear of the day, but now it appears that the same thing happens when we start to lose sleep.

我们晓得,这个顺序在我们睡觉的时分停止,以肃清神经零碎白昼的消耗,但现在好像我们就寝缺乏的时分也会停止相反的顺序。

But rather than being a good thing, the brain goes overboard with the clearing, and starts to harm itself instead.

但是,这并不是什么坏事,大脑会过分肃清细胞,并且开端损伤本人。

Think of it like the garbage being cleared out while you're asleep, versus someone coming into your house after several sleepless nights and indiscriminately tossing out your television, fridge, and family dog.

想一想,这就像你睡觉的时分渣滓桶被清空了,而在你失眠了几个早晨之后,有人离开你家里,恣意地抛弃了你的电视、冰箱和家里养的小狗。
