an exellent edit Dave!

[edit] Figure

I don't much like the action potential diagram and part of the text, because it equates the undershoot with the refractory period. While the undershoot does make it a longer distance to threshold, the main cause of the refractory period is sodium channel inactivation, which actually moves the threshold to more depolarized levels.

The other problem with the diagram is that the amplitude of the undershoot is too big. It goes well below Ek, the theoretical limit of hyperpolarization. I re-did this drawing in action potential with a shallower undershoot, and taking off the label calling it the refractory period. Feel free to use it. Synaptidude 9 July 2005 07:00 (UTC)

I changed the figure to the Part A of the figure that is used in the action potential article. --Memenen 9 July 2005 12:52 (UTC)

Great! Thanks. Sorry, that must have been some work. I should have uploaded each part of the figure separatly Synaptidude 9 July 2005 16:37 (UTC)

I suggest putting part A and Part B of the figure like this:

A
B

on the action potential page. --Memenen 9 July 2005 16:50 (UTC)

can do, but not until Monday Synaptidude 9 July 2005 16:52 (UTC)

I do not agree with the interpretation of the quote from Lodish. I interpreted the phrase "initially hyperpolarizes the membrane" to refer to the undershoot period, which is a true "hyperpolarization" i.e. more polarized than it usually is. I'm guessing that its bad phrasing on their part. 70.137.91.186 05:34, 22 January 2007 (UTC)

Wait a minute. If that reference is incorrect, why is it in the references section? shouldn't it be in a "Notes" section or something? --Exec. Tassadar (comments, contribs) 10:33, 21 February 2008 (UTC)
