Hello,
How do I describe a non uniform distribution of conductance density over a section for a ion channel?
In other words, given a section divided in multiple segment, I assign a specific value of conductance density to each segment.

I would like to simulate the behaviour of an isotropic medium with an axial transfer resistance of 1.65-3.9 (ohm m), which is the experimental finding for axial transfer resistance ( "In Vivo Measurement of Cortical Impedance Spectrum in Monkeys: Implications for Signal Propagation" Logoth...

It's 1e+09 mho/cm2.

Nothing.
I keep the xg default value.

I've implemented a simple simulation with a passive cylindrical section (400 um long, 1 um diam) and an external oscillating electric field at 50 Hz. I don’t see any difference when I change the extracellular capacitance from its default value of 0 (the xc[0] or xc[1] in the extracellular mechanism)...
