The assessment of the strength of interaction between neurons of the motor cortex of the cat in a conditioned reflex to time.
The study was carried out in cats, with the recording of multineuronal activity of the motor cortex during the development of a conditioned reflex to time. The strength of the interaction between adjacent and remote neurons within a range of 0.5 mm was assessed. The dynamics of the strength of the interneuronal interaction did not correlate in the overwhelming majority of cases with the dynamics of the frequency of the impulse activity of the neurons under investigation. Changes in the strength of interaction between neurons separated from one another in a conditioned reflex (CR) to time were encountered more often than between adjacent neurons; this may serve as additional evidence in favor of the hypothesis of the more rigid structure of connections within microsystems and the greater plasticity of connections between microsystems.
