This article desperately needs a rewrite. This page is almost useless to me as a student. Thanks. . . 168.122.171.113 22:29, 7 October 2007 (UTC)[reply]

LOL. OK I'll try to add to it, although, there really isn't much information available on the hillock. To be honest with you, even if you read the best text books (From Neuron To Brain or Neuroscience), they sometimes use vague language...the descriptions of the axon hillock are no exceptions.

I agree. There was a lot of repetition, and many bullet points at the end that were not incorporated into the main text. I've just made a fairly radical re-write that I hope improves things a little. If you feel I've deleted any useful information, please re-add it. Much more work is need though, and there are still no references. Jamesscottbrown (talk) 17:32, 12 June 2009 (UTC)[reply]

Origin of Action potential

"For many years it was believed that the axon hillock was the usual site of action potential initiation." I would need a citation here. For many years, because of a propagated mistake in textbooks, the words "axon hillock" where used to describe the "axon initial segment". In all those textbooks, the accompanying drawing represented the initial segment, not the axon hillock at all. And any electron microscopist knew the difference. The hillock is not part of the axon, it is part of the soma. It does not contain microtubules. This widespread error was one of our favorite ranting when I was doing my PhD as a molecular neurobiologist 20 years ago. As far as I am aware, it was never believed that the action potential initiated on the soma of the neuron. Nicolas Le Novere (talk) 11:20, 16 November 2011 (UTC)[reply]

Trigger zone

I believe there is a particular portion of the Axon hillock known as the "trigger zone" which is especially conductive. May want to look into this 129.180.166.53 (talk) 14:51, 10 June 2012 (UTC)[reply]
