Presets
The Hodgkin-Huxley model — the Nobel-winning description of the nerve impulse — tracks voltage and the opening of sodium and potassium channels. Below a threshold current the neuron is silent; above it, it fires a train of action potentials whose rate climbs with the stimulus.

Governing equation
Reading this result: Above threshold: each stimulus recharges the membrane fast enough to re-trigger Na⁺ channels, so the neuron fires a repetitive train whose rate rises with the current.
