Modeling branching axons but not DRG

[NaraSakamoto]

Dear all,

I'm looking to model the bifurcation of spinal dorsal root fibers into an ascending and descending dorsal column fiber, similar to the work of Struijk, 1993, and more recent modeling studies on spinal cord stimulation.
This would require daughter axons (smaller diameters) to be attached to the parent axon at a node, but as there is no synapsing point processes perhaps are not applicable. I'm aware that Sim4life support the modeling of DRG and its peripheral and central axons but that's also not what I'm trying to achieve.
Could you kindly share some advise on this, please?
