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.
NREM sleep itself is divided into multiple stages – N1, N2 and N3. Sleep proceeds in 90-minute cycles of REM and NREM, the order normally being N1 → N2 → N3 → N2 → REM. As humans fall asleep, body activity slows down. Body temperature, heart rate, breathing rate, and energy use all decrease. Brain waves slow down.
The study’s first finding is that sleeping between 7 and 9 hours each night was optimal for brain function and boosting cognitive ability. Sleeping less than 7 hours and more than 9 hours ...
This is largely in part because circadian rhythm has a "master clock" that is located in the same part of the brain that is responsible for forming memories, learning, and emotions. [ citation needed ] There has been a push in many educational systems for a later start time to help increase the available time for sleep in adolescents due to ...
