Explanation:
In biology, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. That is, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in the membrane voltage in which the membrane potential is more clearly positive or negative, are hyperpolarizations.
