Abstract
This paper presents Kepiński's concept of “information metabolism”, which attempts to describe processing of the information as an analogy of energy metabolism. It is a biological model based upon the structural organization of the cell. The following terms: control center, boundaries, functional structures, centers of elimination and centers of energy are considered here. The model is complementary to computational models, which are helpful in research and theoretical studies, but not useful in interpersonal contacts. The model of information metabolism aims at explanation of relations between psychological and somatic processes and helps in understanding of psychotherapeutic processes.
