Question

Quizplus · Accepted Answer

Hyperpolarization of the postsynaptic nerve terminal makes the inside of the cell more negative compared to the outside, moving the membrane potential further away from the threshold needed to initiate an action potential, thus decreasing the chance that an action potential will be initiated.
