Derived axial conductance: 0.0 mS/cm² (compartment length: 100 µm)

Myelin raises radial resistance and lowers membrane capacitance; axial resistance remains set by axon radius. Na⁺/K⁺ channel density is reduced under the sheaths.

Scales potassium conductance across all compartments; 100% is the baseline HH density. Myelin's internodal channel reduction still applies.

Each node of Ranvier is bare; increase node width to make it span more compartments.

Node-to-node spacing. The minimum keeps at least five myelinated compartments between nodes.
