Abstract

At the first part of the paper a number of conceptions about psychophysiological mechanisms of reinforcement and its role in brain system activity is presented. At the second part, a significance of the mesolimbic and mesocortical dopaminergic systems in reinforcement process and the relationships between different components of behavioural control (signal, memory, actions, etc.) and intensity of dopamine transmission at the level of n. accumbens and frontal cortex are considered.
