Some of the specific parameters were experimentally estimated for real neurons.
The specific axial resistance RA is 0.6-1 Ω.m (Miller, 1980; Miller et al., 1985;
Fleshman et al., 1988). The value of the specific membrane resistance RM is
0.5-10 Ω.m² (Miller et al., 1985; Cauller, 2003) and for the specific membrane
capacitance CM it is 0.01 F/m² (Miller et al., 1985).

If we introduce a rectangular electric impulse with voltage V, then the voltage
across the membrane changes according to the cable equation:

where

is the time constant (τ) and

λ² =  rm

is the square of the space constant (λ).

In neurons ri » r_e (Sajda, 2002) so we can write:

λ=
