Dielectric property values for mouse hippocampal neurons based on values shown in Table 2 are evaluated, according to experimentally measured CFs. The theoretical CFs in 50% cell media are also calculated in each figure. One property is fit to the experimental values, whereas the other two values are fixed to the values described in each situation. a Cytoplasm dielectric constant values ɛ _c/ɛ ₀ = 40, 60, 75, 85, and 95 are fitted. Smaller values (40, 60) give a slightly better fit. (σ _c = 0.65 Sm⁻¹, c _m = 0.010 Fm⁻²). b Cytoplasm conductivity values σ _c = 0.35, 0.45, 0.55, 0.65, 0.75, 0.85 and 0.95 Sm⁻¹ are fitted. Larger values (0.75–0.95) have a closer fit. (ɛ _c/ɛ ₀ = 60, c _m = 0.010 Fm⁻²). c Membrane effective capacitance values c _m = 0.006, 0.008, 0.01 and 0.012 Fm⁻² are fitted. Larger values (0.01–0.012) provide a closer fit to measured CFs. (ɛ _c/ɛ ₀ = 60, σ _c = 0.75 Sm⁻¹)
