Expand description

Myelinated axon segment — node of Ranvier + internode cable.

Models a single saltatory conduction unit per the MRG 2002 double-cable architecture: an active node (using the NodeOfRanvier model) coupled to a passive internode represented as a lumped RC cable.

The internode has:

Very low capacitance (~0.001 µF/cm², myelin layers)
Very high resistance (myelin sheath insulation)
Paranodal seal resistance (leakage at node-internode junction)

The node voltage drives current through the paranodal seal into the internode, and the internode voltage feeds back into the node via the return path. This bidirectional coupling determines the conduction velocity and safety factor.

The external input represents current arriving from the upstream node (saltatory propagation).

V_node equation: C_n dV_n/dt = I_ionic(node) + g_para*(V_i - V_n) + I_ext V_internode equation: C_i dV_i/dt = -g_l_myelin*(V_i - E_l) + g_para*(V_n - V_i)
