Since this is not my area of expertise, I searched Google under the key words "action potential neuron" to get these possible sources:

http://faculty.washington.edu/chudler/ap.html
http://en.wikipedia.org/wiki/Action_potential
http://www.bris.ac.uk/synaptic/public/basics_ch1_2.html
http://www.blackwellpublishing.com/matthews/channel.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
