Sir Charles Scott Sherrington is one of my science heroes, so I'm featuring him on my cogsci profile. He is often credited with coining the word "synapse."

Since you've contributed a lot to this discussion, I would definitely invite you to combine your comments into an answer, as I've learned quite a bit from them (sometimes you can teach an old Chuck Sherrington new tricks!) @Luke

The N-type Ca++ channels have a range from -40 to -10 mV (from jneurosci.org/content/24/4/797.long), and I believe that they begin to close off after that to prevent excess Ca++ entry into the cell. Again, I think you make a good point, and perhaps the answer should be refined with more details, but I did qualify the comment with the parenthetical statement that there are still gradients. The sodium channels might transiently open, but there is the "foot in the door" type phenomenon that eventually closes them off.

I understand your point, but I'm speaking about a steady state situation instead of a transient one.

@Luke The calcium channels are (in this case) voltage gated, though.
