Inject current into a Hodgkin-Huxley neuron and watch the membrane voltage, the gating variables and the sodium and potassium currents unfold together, from graded subthreshold responses to the all-or-none spike. Measure the threshold, the refractory period and the firing rate, switch to voltage clamp to reproduce the original experiments, and block sodium or potassium channels to see what each does. Three depth levels take it from "channels open and close in sequence" to the full equations.
