[The correlation between the changes in synaptic efficiency and cellular excitability in the acquisition of a conditioned reflex analog].

By calculating correlation coefficients was revealed the positive linear correlation between the conditioned changes of direct and indirect components of the pyramidal tract response pointing to a correlation between changes of synaptic efficiency and coincident shifts of cellular excitability. Coincidence of the maximal value of this connection with that of cellular excitability dependent on the activation of the lateral hypothalamus points to the role of this subcortical motivational structure in starting intracellular reactions leading to a formation of a common molecular substrate underlying interaction of the membrane and synaptic mechanisms. Precedence of the maximal manifestation of this interaction to the highest increase of synaptic efficiency testifies to the contribution of this process to the manifestation of the basic mechanism of conditioned reflex.
