And so that's exactly what happens in this region at the peak of this graph. Now, at the same exact time. Oh, and by the way, if we go back to this section here. So here I said that we have the opening of these voltage gated sodium channels, but the voltage gated sodium channels are not the only ones to open. We also have the opening of the potassium voltage gated on channels. But these potassium voltage gate on channels are very, very slow to open.
