Born and his team have also been able to influence memory recall during sleep - not with sounds, but with odors. In that study, published in March 2007 in Science, researchers asked people to play a memory card game while the smell of roses wafted through a special face mask. Later that night, when the participants were fast asleep, the same odor was delivered to some of them. The following morning, each person played the same game, and the results were clear: the players who got the nighttime rose odor were significantly better at remembering the card pairs than the group...
Beyond sensory stimulation during sleep, the timing of sleep may also be important to memory. Recent research suggests that deep sleep can strengthen factual memories, but only if the person naps within 12 hours of learning. In other words, if you have to memorize an SAT word list, you might be better off doing it at night rather than in the morning...
Although researchers are still a long way from understanding exactly how sleep affects memory, they are certain that getting too little sleep is a detriment. A 2007 paper in Nature Neuroscience reported that in addition to consolidating recently learned memories, "sleep before learning is equally important in preparing the brain for next-day memory formation." The study found that people who had skipped a night's sleep fared worse at making new memories the next day, compared with those who had gotten a good night's sleep.
