What is this? &#8211; Absolute refractory period<br>In the later stages of repolarization, a brief increase in the permeability to potassium<br>occurs and this results in hyperpolarizing the membrane and returning it slowly to its<br>resting value during which time an increasing number of sodium channels can be<br>opened. If you give a strong stimulus, it might be possible for another action potential to<br>occur.
