The action potential is also known as the depolarizing effect, right? Yes. If you do the opposite and make the membrane or the inside of the membrane more negative than its resting potential, you are hyperpolarizing it.

When it becomes positive beyond the resting potential, at least to the, in this case, the threshold.
