Topic: nerve conduction velocity

Axon diameter varies up to 100-fold between distinct neurons in the central nervous system with larger axons exhibiting faster nerve conduction velocity. Further axon diameter influences myelination and its dynamic regulation might help fine-tune the timing of signal propagation and thus neural circuit function. Despite its importance, we know surprisingly little about how axons grow to such different diameters in the living nervous system and which mechanisms underlie this diversity. To fully understand how nervous systems are built, functionally mature, and remain healthy, we need to underst
