The membrane potential at which voltage-gated sodium channels open is called the threshold potential.

Here are the steps that lead to this:

1. Resting Potential: In a resting neuron, the inside of the neuron is negatively charged relative to the outside. This is due to the distribution of different ions on either side of the membrane, and the neuron is said to be polarized.

2. Depolarization: If the neuron receives a signal and the inside of the neuron becomes less negative (i.e., it depolarizes), voltage-gated sodium channels begin to open.

3. Threshold Potential: The specific membrane potential at which enough sodium channels open that the depolarization becomes irreversible is called the threshold potential. This typically is around -55 mV.

4. Action Potential: Once the threshold potential is reached, an action potential is triggered. This is the neuron's way of transmitting information.

5. Repolarization: After the action potential, the neuron repolarizes to restore the negative internal charge.

6. Hyperpolarization: Often, the neuron overshoots and becomes more negative than it was at rest. This is called hyperpolarization.

7. Return to Resting Potential: Finally, the neuron returns to its resting potential and is ready to transmit another signal.
