Does REM sleep help memory?
Research indicates that sleep does more than allow the brain to rest. It may also aid the consolidation of long-term memories. REM sleep and slow-wave sleep play different roles in memory consolidation. REM is associated with the consolidation of nondeclarative (implicit) memories.
