I mentioned the second peak because an action potential actually has two sources of ion current in the waveform, such as (red) Na and (green) K shown below. Where there is a delay before the K channels open its peak shows up later, or that's what I would expect anyway. And it's not necessary to have a negative resting potential as low as fast acting neurons.

The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection.
