Axon diameter and conduction velocity

Range fastest axon ~20µm diameter conduct at ~120 m/s: slowest axon ~0.1µm diameter conduct at ~0.3m/s
Organism Monkey

Comments "In monkeys, for example, the fastest axons are ~ 20 microns in diameter and conduct at ~ 120 m/s. By contrast, the slowest axons are ~ 0.1 micron in diameter and conduct at ~ 0.3 m/s. Thus, the fastest axons occupy ~ 40,000 times the volume of the slowest axons, per unit length and conduct ~ 400 times faster."
