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]]) and deacreses during time spent asleep . Process C describes the ~24h circadian framework in which sleep can occur.
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]]) and deacreses during time spent asleep . Process C describes the ~24h circadian framework in which sleep can occur.
Advantages:
* Good at explaining the basic phenomena of sleep and wakefulness
* Physiological basis for Process S is likely ([[Adenosine-alertness hypothesis]])
Disadvantages:
* No physiological basis for Process C and interaction of Process S & C
* Does not include [[circadian pacemarkers]] and different [[sleep stages]]
