Dreaming May Make You Smarter

做夢也能增強(qiáng)記憶力

People who enjoy a dream-filled sleep are significantly better at recalling information and making links between facts when they wake, scientists found.

科學(xué)家發(fā)現(xiàn)，睡覺愛做夢的人在他們醒著的時候記憶力和關(guān)聯(lián)事物的能力都會顯著增強(qiáng)。

But recharging with a shallow nap offers no such mental boost, the research suggests.

該研究同時也聲明僅僅是打個小盹就不會產(chǎn)生如此神奇的功效。

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.

這一研究印證了先前大量證據(jù)已經(jīng)證明了的一個觀點(diǎn)，那就是快速眼動睡眠（REM）階段對大腦鞏固記憶的能力至關(guān)重要。

An average night's repose includes four or five spells of REM sleep, but these bursts tend to be lengthier towards the end of the night.

在夜間睡眠過程中，通常會有四到五個周期的REM 階段。直到天亮之前，REM 間隔周期呈逐漸延長的趨勢。

This means that adults who get less than the recommended seven to eight hours a night-and therefore insufficient REM sleep-may be damaging their mind's ability to form strong memories.

這就意味著，睡眠時間不足7-8 小時標(biāo)準(zhǔn)睡眠時間的成年人無法保障充分的REM 睡眠時間，因此他們形成牢固記憶的能力有可能會受損。

Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages.

REM 睡眠并不屬于深度睡眠的范疇，只有在經(jīng)過深度睡眠后，大腦才能進(jìn)入REM 睡眠階段。

Scientists have been working on connections between sleep, dreams and brain activity since the REM state was first identified in 1953 by US researchers.

自1953 年美國研究人員首次確認(rèn)REM 睡眠狀態(tài)以來，科學(xué)家一直致力于研究睡眠、夢境以及大腦活動三者之間的關(guān)聯(lián)。

They found that people woken while their closed eyes made jerking movements recalled much more colorful and elaborate dreams than people woken during other stages of sleep.

他們發(fā)現(xiàn)從REM 狀態(tài)中醒來的人，相對那些從其他睡眠狀態(tài)中醒來的人來說，更善于記住豐富多彩的夢境的細(xì)節(jié)。

It is now believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information that needs to be retained from useless information which can be discarded.

現(xiàn)在人們相信，睡眠過程就好比是在大腦內(nèi)部進(jìn)行文案整理工作。隨著儲存的記憶在大腦中進(jìn)行位置轉(zhuǎn)移，

This process may take place as memories are shifted from one part of the brain to others.

大腦從而對相關(guān)信息進(jìn)行區(qū)分——摒棄無用信息，保留有用信息。
