據(jù)近期發(fā)表在《自然—神經(jīng)科學(xué)》Nature Neuroscience上的一項研究顯示,，睡眠能幫助改善一系列手指運(yùn)動的鍛煉,。這使得睡眠對于記憶的重要性再次得到強(qiáng)調(diào)，在睡眠期間對記憶力進(jìn)行選擇性引導(dǎo)改進(jìn)也變成一種可能,。
Ken Paller等人先讓受試者學(xué)習(xí)用鍵盤演奏兩種不同樂曲,。然后讓受試者伴隨著他們所演奏的其中一首曲子小睡90分鐘。通過用腦電圖記錄大腦電流活動,，研究小組發(fā)現(xiàn)在慢波睡眠中,，受試者大腦接收到了樂曲中的一些暗示，而這些暗示此前被認(rèn)為與加強(qiáng)記憶有關(guān),。他們還發(fā)現(xiàn),，與受試者彈奏另一首未在睡眠中播放過的曲子的熟練程度相比，受試者在彈奏睡眠中所聽到的樂曲時出錯較少。
這項結(jié)果表明睡眠過程中接收到的聽覺暗示能夠有選擇地增強(qiáng)與暗示有關(guān)的運(yùn)動技能,，并強(qiáng)調(diào)了睡眠對于改善記憶的重要性,。（生物谷Bioon.com）

Cued memory reactivation during sleep influences skill learning
James W Antony, Eric W Gobel, Justin K O'Hare, Paul J Reber & Ken A Paller
Information acquired during waking can be reactivated during sleep, promoting memory stabilization. After people learned to produce two melodies in time with moving visual symbols, we enhanced relative performance by presenting one melody during an afternoon nap. Electrophysiological signs of memory processing during sleep corroborated the notion that appropriate auditory stimulation that does not disrupt sleep can nevertheless bias memory consolidation in relevant brain circuitry.
