Neural Transmission Velocity

Meaning

Neural Transmission Velocity is the measurable speed at which an action potential, or electrical impulse, propagates along the length of a nerve axon. This velocity is a direct indicator of the efficiency and integrity of the nervous system’s communication pathways, reflecting the health of the myelin sheath and the diameter of the axon. Faster transmission velocity enables quicker processing of sensory information and more rapid, coordinated motor responses. Clinically, a reduction in this velocity often signifies demyelinating pathology or axonal damage, impacting overall neurological function and reflex time.
