The rectified current density distribution is computed for a cell exposed to an electrical field, using the Volterra approach. The cell is simulated by a membrane, composed of a capacitance in parallel with a non-linear resistor, and by external and internal media modelled with a complex dielectric constant. The net current flux on the cell surface is zero: no ion accumulation inside the cell is possible.

Abstract
The rectified current density distribution is computed for a cell exposed to an electrical field, using the Volterra approach. The cell is simulated by a membrane, composed of a capacitance in parallel with a non-linear resistor, and by external and internal media modelled with a complex dielectric constant. The net current flux on the cell surface is zero: no ion accumulation inside the cell is possible. The rectified current density distribution shows a similarity with ionic current loops found in the early developmental stage of the egg of the seaweed Fucus, which suggests possible effects on the development of other cells.File in questo prodotto:
