Primes¶
- Amplification
- The Hodgkin-Huxley model
This sourceModels voltage-dependent ionic conductances generating and propagating the action potential; small perturbations are amplified into all-or-none spikes. SUPPORTS the axonal-signal-amplification claim.
- The Hodgkin-Huxley model
- Refractory Period
- Two sub-regimes are typically distinguished: an absolute refractory window, in which the action is flatly impossible, and a relative refractory window, in which the action is possible but requires a stronger-than-baseline stimulus.
This sourceEstablishes the action potential and sodium-channel inactivation as the mechanism of the absolute and relative refractory periods, the firing-rate ceiling, and one-way propagation.

- Threshold
- When depolarization reaches approximately −55 mV (highly variable across cell types and conditions), voltage-gated sodium channels reach their activation threshold, a self-reinforcing depolarization cascade is triggered, and an action potential is generated, as Hodgkin and Huxley (1952) demonstrated quantitatively in their canonical voltage-clamp characterization of squid-axon membrane currents.
