Saltatory Conduction Race: Myelinated vs Unmyelinated Axon

Race an unmyelinated axon's continuous crawling action potential against a myelinated axon's saltatory node-to-node jumps along an identical distance, then strip away myelin with a demyelination-damage control and watch the live conduction-velocity readout slow — or the signal block entirely.

Compare how a nerve impulse travels along two axons of identical length: an unmyelinated axon, where the action potential must be actively regenerated at every point along the membrane, and a myelinated axon, where the impulse leaps between exposed nodes of Ranvier through electrically insulated internodes. Fire a pulse to race them and watch the live timers, then use the lesion-extent and severity controls to strip myelin from part of the fast axon and see conduction velocity fall — or the signal fail to cross a badly demyelinated stretch entirely.
