[Model of conditioned relex formation and analysis of the functional significance of the electrographic correlates of learning].

The formation of a conditioned reflex was studied on the basis of a net model in which the main data on the interconnection between cortical units were brought. In the course of learning the model reproduced practically the entire complex of electrographic manifestations of conditioning known from experiments. The mechanisms of emergence of theta-activity and spatial synchronization of biopotentials were studied. Attention is drawn to the fundamentally different dynamics of excitability change in the cortical projections of conditioned stimuli and conditioned reaction. The forms of participation of subcortical structures in the formation of conditioned connection are discussed.
