Figure 15.18. Impedance method simulation results: (a) logarithmic colorplot represents
current densities in slice of 3D retinal model (lighter = more current). Note the higher
current densities closer to the current return (top). (b) Line plot showing current densities
for a cross section through the ganglion cell layer. While the four peaks can be differ-
entiated, current density is higher in the leftmost peak, which is closer to the current
return.
