Abstract:
Snail neuronal membranes have two distinct outward current components. Both components are carried by K+-ions. They are, however, differentially influenced by Tetraethylammonium. At low concentrations in the external bath (5 mM), TEA+ blocks the delayed outward current only. The fast outward current is affected if higher TEA+ concentrations are used. Intracellular TEA+, applied iontophoretically, blocks both current components in a similar manner.
