Answer:
Voltage threshold
Step-by-step explanation:
The action potential threshold or voltage threshold is the minimum voltage that the membrane must reach to cause the mass opening of voltage-dependent sodium channels, that is, to trigger an action potential.
The frequency of action potentials, on the other hand, depends on the intensity of the original stimulus.
Only stimuli significant enough to exceed the threshold are transmitted as information and encoded in the form of action potentials along the axon to other neurons.
