Hypnogram showing sleep architecture from midnight to 6:30 am, with deep sleep early on. There is more REM (marked red) before waking. (Current hypnograms reflect the recent decision to combine NREM stages 3 and 4 into a single stage 3.) Understanding the activity of different parts of the brain during sleep can give a clue to the functions of ...
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.

[1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
