Threshold potential
In order for an action potential to be triggered, the membrane potential at the axon hillock of a neuron must exceed the threshold value of approximately –50 mV (relative to the resting potential of –70 mV). This is the threshold potential. If the depolarization remains below this threshold, no action potential is triggered.

All-or-nothing principle
According to this principle, an electrical potential is only triggered in the cell when a certain threshold value of stimulus intensity has been exceeded. The response either occurs completely or not at all.
