[Regulation of plastic properties of electrically stimulated neuronal membrane by noradrenaline].
Noradrenaline perfused into washing solution has been considered for the peculiarities of its effect on plastic properties of electrically stimulated neuronal membrane in snails using a simple learning form--habituation to a rhythmical intracellular stimulus. It is shown that the direction of changes in electrical neuronal response under the effect of amine in concentrations from 1.10(-4) M to 1.10(-8) M towards electrical stimulation depends on peculiarities of the initial genotypical membrane to manifest plastic properties. Initially habituated neurons have shown their ability to restore both the induced and basal AP firing. In contrast to tris nonhabituating neurons have shown plasticity only after noradrenaline perfusion. A modulating significance of noradrenaline in the regulation of plastic properties of the neuronal electrically stimulated membrane is suggested.
