Schematic representation of the electric field lines around or through a spherical cell. The cell membrane conductivity is extremely low. The current flows and the field lines around the spherical cell are distorted. At a certain field value, the membrane allows for the field lines to cross towards the cell interior. Increasing the electric field increases the number of field lines crossing the cell and the cell membrane becomes conductive. Inspired from [86].
