Conduction velocity is the speed at which electrical signals travel along axons and is a crucial determinant of neural communication. Inferences about conduction velocity can now be made in vivo in humans using a measure called the magnetic resonance (MR) g-ratio. This is the ratio of the inner axon diameter relative to that of the axon plus the myelin sheath that encases it. https://www.bekindtopets.com/deal-time-Original-U-S-WWII-193rd-Glider-Infantry-Regiment-Named-Uniforms-with-Garrison-Cap-Jump-Boots-Photos-Documents-and-Mor-limited-save/
