Your question about depolarization
Hello, and welcome to Wikipedia! I saw that you wanted to contact me about that edit at Depolarization. Let me explain it this way. In one part of your edit, you wrote that "At physiological conditions, this generally results in a reduction of negative charge across the cell membrane." That's true, so far, so good. You then wrote, "However, depolarization can also refer to a reduction of positive charge across the cell membrane such as the initial half of the falling phase of an action potential." That's not true. The entire rising phase of an action potential is a depolarization. During the initial part of the falling phase, that depolarization is decreasing in amplitude. That's sometimes called "repolarization". But an increasing negativity of membrane potential cannot be a depolarization, the way that the words are conventionally used. I'm happy to clarify any of that, if you have any questions.

It looks to me like you had a little difficulty leaving me a message. First, as I think you came to realize, it's not done by trying to leave categories. I can point you to Help:Starting editing for an introduction to how to do those kinds of things. But please feel free to leave messages on my user talk page. I'm glad that you have become interested in editing Wikipedia, and I hope that you will continue to do so. --Tryptofish (talk) 15:15, 2 January 2013 (UTC)
