title: [The action of tetraethylammonium on the electrical responses of the neurons of the stretch receptors in the crayfish].
abstract: The effects of intracellular pressure injection of tetraethylammonium and potassium salt solution has been studied for its effect on the receptor potential of the slowly adapting stretch receptor of crayfish. It was found that the pressure injection caused an increase in the static phase of the receptor potential. Intracellular microiontophoretic injection and extracellular application of tetraethylammonium have not exert an effect on the adaptation of receptor potential. The results suggest that tetraethylammonium-sensitive potassium channels are not involved in adaptation of the receptor potential of mechanoreceptors.
