Dr. Jan Born, a neuroscientist at the university, and his team taught volunteers two rules to help them【S4】______a string of numbers into a new order. There was also a third,【S5】______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【S6】______were forced to stay awake. They noticed that the group that had slept after the training were twice as【S7】______to figure out the third rule as the other group. "You have a memory representation in your brain of the problem you want to solve, and then you sleep. Sleep can act on the problem." Born said in a telephone interview. But he also admitted that how【S8】______of memories occurs or what governs it is still unknown.
