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(More)
Substantial differences have been found in the plastic reorganizations of neuronal activity of the rat sensorimotor cortex at local and systemic reinforcements. In nineteen (95%) out of 20 neurones stable and one-type changes of response to CS (electrical stimulation of the cortex) developed in the course of pairings with local ionophoretic application of(More)
Unit activity in the sensorimotor cortex of rats immobilized by d-tubocurarine, was studied at random and paired presentations of sound and microionophoretic application of L-glutamate. 54% of the studied units exhibited specific plastic changes of spike activity in the course of the pairings; the changes were manifested in a significant increase or(More)
