A resting or non-signaling neuron has a voltage over its membrane called the resting membrane potential. It is maintained by two different type of ion channels which are the sodium-potassium pump and the sodium and potassium leak channels.
Resting potential is the unevenness of electrical charge that exists among the interior of electrically excitable neurons or nerve cells and their surroundings.
It is hyperpolarized if the inside of the cell is more electronegative. If the inside of the cell is less negative, it is called depolarization.
