Panel A shows electric potential, obtained using the finite element method following simultaneous activation of several electrodes as shown in the top row. Gray and white circles represent active and non-active electrodes respectively. Panel B illustrates the value of the electric potential underneath the centre electrode of the hexagon as a function of the number of electrodes simultaneously activated with a cathodic pulse.
