Theory of functional systems

Theory of functional systems - is a model that describes the structure of conduct, which was established by Russian and Soviet biologist and physiologist Pyotr Anokhin. Functional systems were put forward by Anokhin as an alternative to the predominant concept of reflexes. Contrary to reflexes, the endpoints of functional systems are not actions themselves but adaptive results of these actions. In contrast to reflexes, which are based on linear spread of information from receptors to executive organs through the central nervous system, functional systems are self-organizing non-linear systems composed of synchronized distributed elements.

"The principle of functional systems" - association of private mechanisms of the body in a holistic system of adaptive behavioral act, the establishment of "integrative unity".

There are two types of functional systems:

• System of the first type provide homeostasis due to internal (existing) resources of the body, inside its boundaries (e.g. blood pressure).
• System of a second type supports homeostasis due to a change of behavior, interaction with the outside world and are the basis of different types of behavior.
