In the simulation when you compared myelination and axon diameter effects on conduction velocity (CV) Question 9 Select one: a. Axon diameter was irrelevant and only myelination mattered b. At small axon diameters, myelination mattered, but not for large axon diameters c. Both mattered equally in affecting CV d. Myelination mattered more than axon diameter in increasing CV e. At large axon diameters, myelination mattered, but not for small axon diameters
