    Abstract:
    State of hunger is characterized by the presence of definite distribution of interimpulse intervals in the activity of sensorimotor cortical neurones (SMC) of rabbit. Mostly bi- and three-modal distribution of interimpulse intervals in the background activity in hungry animals changes in the process of elaboration of food-procuring habit. As the habit consolidates, the SMC neurones acquire the ability to forestalling actions. Peculiarities are revealed of organization of the SMC neurones impulse stream in response to the action of conditioned signal in the case of abolition or substitution of the reinforcement. Repeated substitutions of reinforcement cause the formation of activity of concordance in the moment of substitute "recognition" despite the absence of alimentary reinforcement.
