Sound Sleepers' Brain Waves Block Sounds

酣睡者的腦電波會(huì)屏蔽噪音

Ahhh, sleep. There's nothing better than a nice, long, uninterrupted [LOUD NOISE]. Awwgh. I can't sleep when there's [NOISE]. But d'ya ever notice: noise [NOISE] doesn't wake everyone. Now scientists have a better idea why. Because sound sleepers show a certain brain rhythm when they doze, findings published in the journal Current Biology.

啊……睡覺(jué)是多么美妙??！再?zèng)]什么比得上美美地睡一個(gè)香甜悠長(zhǎng)的好覺(jué)了，當(dāng)然還要不受打擾（巨大的噪音）……呃……在電閃雷鳴之時(shí)（打雷聲）我可睡不著，不過(guò)你是否注意到，并不是每個(gè)人都會(huì)被喧鬧聲（小號(hào)聲）吵醒。如今，科學(xué)家們對(duì)于這一現(xiàn)象有了更好的解釋。根據(jù)《現(xiàn)代生物學(xué)》雜志上刊登的研究結(jié)果，這是因?yàn)槭焖咴诖蝼龝r(shí)會(huì)顯示出某種腦波律動(dòng)。

To study the brain waves of a good night's sleep, scientists invited volunteers to snooze in the lab. While the subjects caught some Zs, the researchers monitored their brain activity. They then subjected the sleepers to [NOISE] or [NOISE]. And they found that those who were able to slumber straight through all the [NOISE] showed more short bursts of faster brain waves. This activity, the scientists say, is the brain's way of blocking out the [NOISE] and the [NOISE] while you're trying to rest.

為了對(duì)夜晚好眠時(shí)的腦電波進(jìn)行研究，科學(xué)家們請(qǐng)志愿者在實(shí)驗(yàn)室里打盹兒。當(dāng)他們開(kāi)始鼾聲連連時(shí)，研究人員就監(jiān)測(cè)他們的大腦活動(dòng)，然后再給入眠者制造些噪音（鈴聲、喇叭聲）。他們發(fā)現(xiàn)那些對(duì)噪音毫不理會(huì)、依舊呼呼大睡的志愿者會(huì)顯示出更多更快的短脈沖腦電波。科學(xué)家們稱，這種腦部活動(dòng)是人們?cè)谛菹r(shí)大腦屏蔽噪音（摔東西聲、狗吠）的一種方式。

The scientists don't yet know of any way to boost those sleep-saving brain waves. So until then, shut the door [DOOR SHUTTING], make sure the late show's on a timer [TV SOUND], and try to have sweet dreams.

科學(xué)家們還不知道有什么方法可以增強(qiáng)那些能夠保證睡眠的腦電波。因此，在有效方法找到之前，關(guān)上房門(mén)（關(guān)門(mén)聲），確保夜間節(jié)目別看到太晚（電視節(jié)目聲），然后進(jìn)入甜蜜夢(mèng)鄉(xiāng)吧。
