When you learn something new, the best way to remember it is to sleep on it. That's because sleeping helps strengthen memories you've formed throughout the day. It also helps to link new memories to earlier ones. You might even come up with creative new ideas while you slumberIn the last century, scientists have tested this theory many times, often finding that sleep improves memory retention and recall by between 20 and 40 percentWorking memory performance declines under conditions of sleep deprivation. These performance decrements are associated with a change in neural activation throughout the brain, particularly in the frontal and parietal areasConverging evidence suggests that dreaming is influenced by the consolidation of memory during sleep. Following encoding, recently formed memory traces are gradually stabilized and reorganized into a more permanent form of long-term storage.
