A theoretical model of ionic to electronic current transition for cells cultured on a conductive substrate. The ionic current interacting with electrons could direct their flow in other directions. This electronic current, opening the voltage-gated ion channels, would result in the influx of Na+, K+ and Ca2+ ions. This influx will depolarise the plasma membrane and the passive group (PG) will eventually fire action potentials.
