Slow Wave Sleep (SWS) is a highly active state unlike a state of brain quiescence as previously thought. Brain imaging data has shown that during NREM sleep the regional brain activity is influenced by the waking experience just passed. A study was done involving an experimental and a control group to have them learn to navigate a 3D maze.
Slow-wave sleep (SWS), often referred to as deep sleep, is the third stage of non-rapid eye movement sleep (NREM), where electroencephalography activity is characterised by slow delta waves. [ 2 ] Slow-wave sleep usually lasts between 70 and 90 minutes, taking place during the first hours of the night. [ 3 ]
NREM parasomnias are arousal disorders that occur during stage 3 (or 4 by the R&K standardization) of NREM sleep—also known as slow wave sleep (SWS). They are caused by a physiological activation in which the patient's brain exits from SWS and is caught in between a sleeping and waking state.
A new study offers an explanation as to how deep sleep — also known as slow wave sleep — helps support the formation of memories in the brain, which could help with preventing dementia.
The authors wanted to know whether chronic reductions in slow-wave sleep over time are linked with dementia risk in humans and vice versa — whether dementia-related processes in the brain may ...
The optimal nap duration is around 10–20 minutes, as researchers have proven that it takes at least 30 minutes to enter slow-wave sleep, the deepest period of sleep. [44] Napping too long and entering the slow wave cycles can make it difficult to awake from the nap and leave one feeling unrested. This period of drowsiness is called sleep inertia.

Polysomnogram demonstrating slow-wave sleep. High amplitude EEG is highlighted in red. Slow-wave sleep (SWS), also known as Stage 3, is characterized by a lack of movement and difficulty of arousal. Slow-wave sleep occurring in both hemispheres is referred to as bihemispheric slow-wave sleep (BSWS) and is common among most animals.
