During sleep, memories locked in the brain's short-term storage migrates into a longer-term database, according to a new study that backs up the benefits of midday power naps.
Although the "dreaming" sleep stage known as REM is perhaps better known, humans actually spend about half of the night in stage 2 non-REM.
REM sleep is crucial for more complex thinking, such as making nonobvious connections between previously learned facts—a process he describes as "a Google search gone wrong—or right."
