As for the small mammals, delta-power provided a good estimate of the sleep cycle in humans (see bottom panel). Fig. 3: Example sleep recording of tree shrews, rats, and humans. a Top, spectrogram of an 8 h recording period for an example tree shrew. Middle, hypnogram showing NREM...
Perivascular spaces are important highways for fluid and solute transport in the brain enabling efficient waste clearance during sleep. However, the underlying mechanisms augmenting perivascular flow in sleep are unknown. Using two-photon imaging of naturally sleeping male mice we demonstrate sleep cycle-...

[88,89]. The largest amount of evidence is available for the method of selective breathing cycle-controlled HNS. Extensive clinical data are available from a controlled multicenter study with randomized treatment withdrawal and also from a 5-year follow-up period. Many other controlled studies as ...
The temporal sequence of SWS and REM sleep in the normal sleep cycle suggests that these sleep stages have complementary roles in memory consolidation: during SWS, system consolidation promotes the re-activation and redistribution of select memory traces for long-term storage, whereas ensuing REM slee...
