REM Sleep Reactivation Locks Memories in Place

Rare adult-born neurons in the hippocampus are reactivated during REM sleep, locking waking experiences into long-term memory. Using genetically modified mice, they found that these neurons fire in the same patterns during sleep as they did during learning.

Learning Gains While We Sleep Originate From the Learning Process Itself and Not Just From Using the Brain

Learning consolidation that occurs during sleep is a result of the learning process, and is not simply due to neural processes and brain regions associated with learning.

Dreams Reflect Multiple Memories and Anticipate Future Events

53% of dreams can be traced to memories, and of those, 50% are linked to memory sources of multiple previous life events. Additionally, 26% of dreams are associated with impending events. Future-orientated dreams become more prevalent during deeper stages of sleep.

How the Brain Strengthens Memories During Sleep

The reactivation of learned material during slow oscillation/sleep spindle complexes, and the precision of SO-spindle coupling predicts how strong a memory will be reactivated in the brain.
