研究人员发明,经久睡眠缺乏会使大年夜脑清除大年夜量神经元和突触连接,并且恢复睡眠或许其实不克不及完全修复毁伤。

睡眠与大年夜脑.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.

人们对睡眠的需求不只仅是为了每12个小时弥补一下体力。实际上,我们睡觉的时辰,大年夜脑会改变状况,清除日间神经活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.

奇怪的是,经久睡眠缺乏,大年夜脑内也会停止如许的法式榜样,只是它会进入过度清除状况。

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.

研究人员发明,经久睡眠缺乏会使大年夜脑清除大年夜量神经元和突触连接,并且恢复睡眠或许其实不克不及完全修复毁伤。

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.

意大年夜利马尔理工大年夜学神经迷信家米歇尔·贝蕾西带领的团队研究了哺乳植物的大年夜脑对睡眠缺乏的反响,他们发明歇息时间充分的小鼠与睡眠缺乏的小鼠之间有古怪的类似性。

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,你大年夜脑里的神经元也在赓续被两种不合的神经胶质细胞所更新,这些支撑细胞常常被称为神经体系的粘合剂。

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

这类微神经胶质细胞经过过程一个被称为吞噬景象(phagocytosis在希腊语中是“吞噬”的意思)的过程来清除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.

星型胶质细胞的感化是清除大年夜脑中不须要的突触(连接)来恢复偏重塑它的神经搜集。

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.

我们知道,这个法式榜样在我们睡觉的时辰停止,以清除神经体系日间的消耗,但今朝仿佛我们睡眠缺乏的时辰也会停止雷同的法式榜样。

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

但是,这其实不是甚么功德,大年夜脑会过度清除细胞,并且开端伤害本身。

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.

想想,这就像你睡觉的时辰渣滓桶被清空了,而在你掉眠了几个早晨以后,有人离开你家里,任意地扔掉落了你的电视、冰箱和家里养的小狗。
