Solution

The correct answer is "depolarization; hyperpolarization".

Depolarization refers to the membrane potential becoming more positive in value. This happens when the neuron is stimulated and the negatively charged ions inside the neuron are replaced by positively charged ions.

Hyperpolarization, on the other hand, refers to the membrane potential becoming more negative than the resting membrane potential. This happens when the neuron is inhibiting and the positively charged ions inside the neuron are replaced by negatively charged ions.
