Cells become more negative during hyperpolarization.

Question

Quizplus · Accepted Answer

During hyperpolarization, the membrane potential becomes more negative than the resting potential, which is typically around -70mV in neurons. This is due to the opening of potassium channels or the closing of sodium channels, resulting in an efflux of potassium or the prevention of sodium influx. As a result, the cell becomes more negative, making it more difficult to depolarize and initiate an action potential.
