- Both regions proximal and distal to the injury
What potential do neuronal circuits in the peripheral nervous system have following an injury?
What potential do neuronal circuits in the peripheral nervous system have following an injury?
- They have the potential for reorganization through the formation of new synapses
- They have no potential for reorganization
- They have the potential for reorganization through the regeneration of injured fibers
