Stepwise action potentials of the soma membrane of molluscan neurons

  • Published:
Neurophysiology Aims and scope

Abstract

Experiments were carried out on neurons of the visceral complex of ganglia ofHelix pomatia. Application of strong hyperpolarizing stimuli ("electro-convulsive shock") throughan intracellular microelectrode led to dissociation of the original action potential into small components. Repetition of the "electro-convulsive shock" intensified these phenomena. Regular hyperpolarizing stimuli led to the formation of action potentials whose amplitude depended on the intensity and duration of the hyperpolarizing stimuli. The possibility that trigger zones are located on the soma membrane of molluscan neurons is discussed on the basis of the results.
