And this is known as repolarization, because as the charge moves out, the inside of the membrane will once again become negatively charged. And so, because we have the inactivation of these potassium of these sodium voltage gate channels and the activation of these potassium voltage gate on channels, it actually goes below that negative 70 millivolt value. And this is known as the hyperpolarization period. And eventually there will be a closure and in some cases, an inactivation of these potassium voltage gate on channels. And so that will basically help return that voltage difference back to normal. Of course, with the help of that sodium potassium Atpace pump, eventually that resting membrane potential is returned back to normal to value of negative 70 millivolts.
