... 4. The voltage sensitive Na+ gates only stay open a moment and then K+ gates open. These allow K+ to rush out of the axon, bringing it back to a negative charge (when called this repolarization or hyperpolarization). 5. Although the charge is back to rest, the Na+ and K+ ions are on opposite sides ...
