Figure 8.

The extracellular potential around a neuron shaped as a rectangular cuboid computed by the stationary versions of the EMI, CBV, CP, and CS methods. The plots to the left 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 neuron. The plot to the right shows the extracellular potential along a line 2 μm above the neuron in the y-direction and in the center of the domain in the z-direction. We use the parameters specified in Table 2 except for L_x = L_y = L_z = 120 μm and $g_L=3·10^{-5}$ μS/μm². The abbreviations (EMI, CBV, CP, and CS) are summarized in Table 1.
