Sleep and learning
open-in-new
<p> Multiple hypotheses explain the possible connections between sleep and learning in <a href="/facts/Human/rlcTENsr">humans</a>. Research indicates that sleep does more than allow the brain to rest; it may also aid the consolidation of long-term memories. </p><p>REM sleep and slow-wave sleep play different <a href="/facts/Sleep_and_memory/rYq8QMMF">roles in memory consolidation</a>. REM is associated with the consolidation of nondeclarative (implicit) memories. An example of a nondeclarative memory would be a task we can do without consciously thinking about, such as riding a bike. Slow-wave, or non-REM (NREM) sleep, consolidates declarative (explicit) memories. These are facts that need to be consciously remembered, such as dates for a history class. </p>
