Voltage field in a vertical plane that cuts through the center of the model. Absolute values of the voltages are plotted on a logarithmic scale shown on the right. The neuron is located where the maximum voltages are observed. The small box delineates the region with extremely fine mesh containing the array and the neuron. Both positive (above the neuron) and negative (below the neuron) voltages are shown on the same color scale using the absolute values
