[Dynamic stereotype as a systemic property of the brain].

Based on the theory of functional systems, the author has developed I. P. Pavlov's idea on the dynamic stereotype--"reality imprints". The parameters of reality, and the results of actions in particular, that meet the leading requirements of living organisms are shown to be dynamically imprinted as molecular engrams of an acceptor of results of actions on the structures involved in dominating motivation. Dominating motivations play a key role in extracting early formed acceptor engrams of results of activities in different functional systems.
