Passive cable response to constant input current for varying space constant λ̂ of test neuron. A: steady-state depolarization of population-averaged Vm; same as Fig. 3B. B: steady-state response of “test neuron” V̂m. Space constant λ̂ of test neuron is varied so that it is smaller than (green), the same as (blue), or larger than (red) space constant of cables in population. Space constant for cables in population is λref (half the physical length of the cable) in all simulations. C: steady-state Ve response produced by population of cables; same as Fig. 3D. x-Axis shows dimensionless distance along cable relative to the reference space constant (half the physical length of all cables).
