====Two-process model of sleep====

The two-process model of sleep is a conceptual model that aims to relate the behavioral state regulation to two main procedures. Process-S describes the increasing homeostatic pressure, the more time spent awake (Adenosine-alertness hypothesis link) and deacreses during time spent asleep  . Process C describes the ~24h circadian framework in which sleep can occur.
