What is the action potential of the plasma membrane of a neuron?

1. The electrical potential difference across the plasma membrane when the neuron is resting.
2. The electrical potential difference across the plasma membrane at the site of excitation when the membrane is depolarised.
3. The electrical potential difference across the plasma membrane when the membrane is in a non-polarised state.
4. The electrical potential difference across the plasma membrane when the membrane is in a polarised state.
