While Your Body Is Resting, Your Brain Is Working Faster

A new study reveals that the brain "replays" activity from the day during sleep to sort through and consolidate memories. The brain activity patterns that consolidate memories while we sleep work at an impressive rate, according to research published last week in the journal Cell Reports. "By understanding how sleep helps memory, it may be possible in the future to assist the people with memory deficits by manipulating their sleep patterns," Mellor told The Huffington Post. "The reactivated patterns of activity found during sleep are much faster than the original patterns during waking," Mellor said.
