    Abstract:
    A new cellular analog of temporary connection has been elaborated on a micropool of neurones in the sensorimotor cortex. Transmitters -- glutamate and acetylcholine, microionophoretically applied near studied neurones, served as paired signals. In case of initial reactivity to paired stimuli, a stronger excitatory effect of the US analog in comparison to that of the CS analog, all studied neurones of the micropopulation developed, within the area of the transmitters' action (less than 100 mc), specific associative rearrangements: enhancement in reactivity to the signal stimulus and reproduction of the reaction to US in response to CS. In control experiments with pseudoconditioning and reverse order of presentation of the same paired stimuli, no rearrangement was observed.
