[Change in neuronal membrane permeability exposed to adenosine-3',5'-cyclophosphate].
Ionic current induced by intracellular injection of cAMP was divided into constituent parts, and the dependence of these components on membrane potential and ionic composition of extracellular medium was demonstrated. The computation shows that practically all background neurone permeability for potassium ions is cAMP-dependent.
