And that's because as we begin to approach this value, some of these actually become inactivated. So remember, about a millisecond after we actually open these channels, they begin to close as a result of the occlusion, as a result of the blocking action of this chain. So, based on the ball and chain model, we know that this ball will basically move into that pore and that will block and inactivate the movement of these ions. 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.
