Propagation and Synchronization of Potential Pulses between Self-sustained Membrane Oscillation Systems

Abstract

The mechanism of propagation or synchronization of self-sustained potential oscillations between two-membrane systems has been proposed. Two aqueous phases W1 and W1' were connected through common phases of nitrobenzene phase, O, and pure water phase, W2. It was demonstrated that the potential pulse was propagated together with an interfacial spreading of surface-active substance, and the accession of the pulse to another oscillation site induced the synchronized oscillation pulse. On the other hand, the faster propagation of the potential pulse was realized due to the interfacial blocking of the O/W2 interface, but the propagation due to the bulk conduction did not induce the synchronization of self-sustained oscillation.
