And so we also have an actual potential traveling this way. Why doesn't that actually take place? Well, it turns out that this region that is being rep polarized is actually experiencing an absolute refractory period. And that means that all the sodium gated channels are actually closed, all the sodium voltage gated channels are actually closed and inactivated. And that means no matter how high the stimulus is, no action potential can be generated in the region right before our action potential. So once again, you might be wondering why the action potential does not move back towards our cell body.
