Why does a hyperpolarization phase generally follow a repolarization phase in an action potential?
What will be an ideal response?
Immediately after an action potential the potassium gates, being slow gates that do not respond to change in the electrical charge, allow additional K+ ions to flood into the cell. These K+ ions decrease the positive ion concentration momentarily below the normal -70mV and thus hyperpolarize the cell.
