Injected current (µA/cm²)

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

C_{m} \frac{d V}{d t} = 10 - \overset{g}{ˉ}_{N a} m^{3} h (V - E_{N a}) - \overset{g}{ˉ}_{K} n^{4} (V - E_{K}) - \overset{g}{ˉ}_{L} (V - E_{L})

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.
