Stimulate a 3D axon to find the threshold and the all-or-none law, then scrub through a membrane close-up as Na⁺ and K⁺ channels open and close and the membrane potential graph is drawn. Add myelin to time saltatory conduction, and see how a reuptake inhibitor and a receptor blocker change the signal in the next neuron at a synapse.
