The action potential has three … Witryna20 mar 2024 · Action potentials are large changes in the membrane potential of a neuron triggered by a stimulus. These potentials are generated when an electrical impulse, or "spike", travels along a neuron's axon. Action potentials cause a rapid, all-or-none response and initiate any further transmission of signals along the neuron.
