Maximum difference between the solution for the extracellular potential in Ω_e\Γ computed by the EMI method and each of the other methods for the test cases in Figure 9.

Method	Maximum difference (mV)	Relative maximum difference (%)
(A) Neurons separated by 10 μm
CBV	0.025	12.6
CP	0.087	43.2
CS	0.086	42.4
(B) Neurons separated by 4 μm
CBV	0.014	5.2
CP	0.141	52.9
CS	0.128	48.3

The relative maximum differences are computed as the maximum difference divided by the maximum absolute value of the extracellular potential computed by the EMI method. The abbreviations (EMI, CBV, CP, and CS) are summarized in Table 1.
