How does a neuron return to resting membrane potential after hyperpolarization?
The hyperpolarization of the membrane potential relative to the resting potential (the undershoot) causes voltage-dependent Potassium conductance (and any Sodium channels not yet inactivated) to turn off, allowing the membrane potential to return to resting level.

If any of these are not a genuine rephrasing of the question, please help out and edit these alternates.
What is hyperpolarization?  Hyperpolarization leads to what?  What helps return neuron back to resting?  Membrane resting potenial is a result of what?  The neuron membrane is before the start of potenial?  What mechanism returns the membrane potential from plus 35 mV during the peak of the action potential to resting levels?
