Detailed explanation-1: -Hyperpolarization prevents the neuron from receiving another stimulus during this time, or at least raises the threshold for any new stimulus. Part of the importance of hyperpolarization is in preventing any stimulus already sent up an axon from triggering another action potential in the opposite direction.
Detailed explanation-2: -Why is hyperpolarization a necessary state for a muscle fiber to experience before a second action potential can be initiated across the sarcolemma? Hyperpolarization is needed to reset the voltage-gated sodium channels.
Detailed explanation-3: -Hyperpolarization-that is, an increase in negative charge on the inside of the neuron-constitutes an inhibitory PSP, because it inhibits the neuron from firing an impulse.
Detailed explanation-4: -Depolarization and hyperpolarization occur when ion channels in the membrane open or close, altering the ability of particular types of ions to enter or exit the cell. For example: The opening of channels that let positive ions flow out of the cell (or negative ions flow in) can cause hyperpolarization.
