It is one thing to learn a new piece of information, such as a new phone number or a new word, but quite another to get your brain to file it away so it is available when you need it.

　　學習新知識——比如記個電話號碼或者一個新單詞——是一回事，而將它們存進大腦并在需要時調用就完全是另外一回事了。

　　A new study published in the Journal of Neuroscience by researchers at the University of York and Harvard Medical School suggests that sleep may help to do both. The scientists found that sleep helps people to remember a newly learned word and incorporate new vocabulary into their "mental lexicon".

　　英國約克大學和美國哈佛醫學院聯合在《神經科學雜志》刊登的研究論文稱，睡眠能夠兼修學習能力和記憶能力?？茖W家們發現，睡眠可以幫助人們記住新學到單詞，并將其納入“人腦詞典”。

　During the study, researchers taught volunteers new words in the evening, followed by an immediate test. The volunteers slept overnight in the laboratory while their brain activity was recorded using an electroencephalogram. A test the following morning revealed that they could remember more words than they did immediately after learning them, and they could recognize them faster demonstrating that sleep had strengthened the new memories.

　在研究中，研究人員在晚上教會志愿者新單詞，隨后立即測試。然后志愿者在實驗室入睡，研究人員同時檢測腦電波以觀察他們的大腦活躍度。次日早晨的測試結果證明，志愿者睡后記住的單詞比剛學完記住的單詞還要多，并且能很快回想起新學單詞，這表明睡眠有助于加強新記憶。
