Hyperpolarisation occurs after repolarisation in the process of an action potential. During repolarisation, voltage gated potassium channels open and potassium floods out of the cell down its concentration gradient. During hyperpolarisation, these voltage gated potassium channels are slow to close and therefore potassium continues to leave the cell. This causes the membrane potential to drop below the resting potential.
