Abstract <p>The organization of psychological structures in a strategic game is described as heterogeneous semantic network in terms of components and nine types of logical relations. Each component contains two sets of informational models of interaction: individual with the subject fields (first kind) and with other components (second kind). The analysis of neuronal basis of semantic network is aimed to define ontological status of components and their interactions. Each type of logical relations between components corresponds to certain type of ontological interrelations between informational models of the second kind. So, the main factor of heterogeneity of semantic networks could be complex organization and polysemy of their components (entities), i.e., the coexistence of many informational models fixed on the same component, and their simultaneous actualization and permanent complication.</p>
