Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
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. An example of a nondeclarative memory would be a task that we ...
Sleep deprivation may additionally affect memory by reducing the proliferation of cells in the hippocampus. [51] Sleep deprivation has also been associated with decreased overall membrane excitability of neurons in the brain. Activation of these membranes is critical for the formation of memories. [52]
Playing sounds to people while they sleep could help them forget specific memories, a new study suggests. Researchers said the method could one day be developed into a technique to help combat ...
New research finds that sleep 'resets' neurons in certain brain areas, which helps the brain more effectively create new memories the next day.
Irregular sleep schedules can cause negative impacts on learning, memory, and performance. The dual process theory determines that certain types of memory depend on specific sleep states, like REM and NREM (Non-Rem) states. REM sleep deprivation can reduce sleep-induced improvement such as visual perception, thus influencing how one learns.

"Sleep pressure and circadian rhythms", the driving forces and the framework of sleep, are brought up by Walker in the book. Other sleep behaviors, such as non-rapid eye movement sleep and rapid eye movement sleep, and the impact sleep has on "synaptic pruning" and the creation of memories during a human's lifespan are also covered.
