Hyperpolarization
Step-by-step explanation:
Hyperpolarization of neurons in turn results in the need for a stronger than normal stimulus in order to trigger an action potential (action potential is an efficient signaling process by which distantly located cells communicate to each other)
To trigger an action potential cells must reach threshold (critical electrical value required to open voltage-gated ion channels)
If the membrane potential is hyperpolarized and falls below normal resting membrane potential, then more cations must enter the cytoplasm for the cell to reach threshold
