speeds can be boosted with myelination and increased axon diameter

Speed is distance divided by time,so this signal travels somewhere between 120 to 240 kilometers per hour.The initial action potential accounts for 1 to 5 milliseconds and synaptic transmissions only take .1 to .5 milliseconds,so the bulk of that time is spent within the axons.This is consistent with research findings that the average individual neuron sends signals at around 180 kilometers per hour.But speeds can be boosted with myelination and increased axon diameter.Myelin is a fatty sheath that insulates an axon,preventing electrical currents from leaking out.Meanwhile, axons with larger diameters offer less internal resistance.
