　　Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that seemed impossible to solve the night before can often appear easier, although no evidence has proved this by now. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight(洞察力）and problem-solving. “If you have some newly acquired memories in your brain, sleep acts on these memories, restructures(重构）them, so that after sleep the insight into a problem which you could not solve before increases,” said Dr. Jan Bom, a neuroscientist, at the university. To test the theory, they taught volunteers two simple rules to help them put a string of numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups, half were allowed to sleep after the training while the remainders were forced to stay awake. Bom and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group. “Sleep helped,” Bom said in a telephone interview. “The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep, so it can act on the problem.” But Bom admitted that he and his team don’t know how restructuring of memories occurs or what governs it or in which stage of sleep it works. Pierre Marquette and Pierre Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can promote creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep, they added.
