The quiet rest and non-REM sleep groups showed no improvement in their test results, but the REM sleep group improved on their morning performance by an average of almost 40 per cent.

對于分別進行簡單休息和無快速眼動睡眠小憩的兩組參與者，他們實驗結果并沒有任何進步；而進入快速眼動睡眠的一組測試者，他們早上的測試成績提高了近40%。

Dr Sara Mednick, a sleep researcher at the University of California in San Diego who led the study, believes that the formation of connections between previously unassociated information in the brain – which leads to creative problem-solving – is encouraged by neurological changes which occur during REM sleep.

該研究負責人，加州大學圣地亞哥分校睡眠研究員薩拉•梅德尼克認為，大腦把之前儲存的信息聯系在一起，并最終形成創造性的解決問題的方案，這整個過程的催化劑便是快速眼動睡眠中發生的神經變化。

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快速眼動睡眠狀態以來，科學家一直致力于研究睡眠、夢境以及大腦活動三者之間的聯系。
