Abstract
There are many unsolved phenomena in the nerve transmission, such as the threshold of the membrane potential to change from resting potential to action potential, the directionality of the nerve conduction, etc. Since it is difficult to measure local membrane potentials of an actual nerve cell, the propagation of a change in the potential difference across a liquid membrane from a potential-sending site to a potential-receiving site along the membrane surface was studied by using a cell system combined with several liquid membrane cells composed of two aqueous phases and 1,2-dichloroethane phases. The change in membrane potential began to be caused by the local circulating current and was gradually propagated to the distant area.
