Figure 6.

Extracellular potential computed by the stationary EMI model for four different values of Δx = Δy = Δz. We show the solution in a rectangle of size 60 × 30 μm on the plane in the center of the domain in the z-direction. The white area represents the cell. We use the parameters given in Table 2 except for an increased value of $g_L=3·10^{-5}$ μS/μm² and a domain of size 60 × 60 × 60 μm.
