I think there should be an article regarding grey matter in terms of physics, I would happy to expand on the topic, but I feel I am in a position to elaborate on my expressions in terms of theory initially. <small><span class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Davidyevgenyroven|Davidyevgenyroven]] ([[User talk:Davidyevgenyroven|talk]] • [[Special:Contributions/Davidyevgenyroven|contribs]]) 01:05, 10 August 2012 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot--> |

"In addition, grey matter does not have a myelin sheath and does not regenerate after injury unlike white matter." Is this true? I thought that new(ish) research indicates that grey matter can regenerate, although it's not certain whether it can connect to the rest of the brain in any meaningful manner. http://healthlink.mcw.edu/article/926345803.html
- In addition to this, it says earlier in the article that grey matter has "few myelinated axons", and later none. --aciel 19:24, 14 October 2005 (UTC)
- In addition to this, new research published by Yale university has shown that meditation is associated with an increase in grey matter indicating that grey matter can be grown.

Sentence removal
I have removed the following sentence/paragraph because it sounds silly. I think a better source is required if one is going to make claims about "intelligence-related" grey or white matter differences between sexes. To the lay reader, this sentence is, at the least, not very well written, and at worst, carries POV connotations—though I don't claim POV is intended. Especially as a paragraph unto itself, with no context, it comes across oddly. (Note: the most recent edit was the "(definitions crucially needed)" segment, which really doesn't belong in the sentence proper.)
- In general, men have nearly 6.5 times more intelligence-related (definitions crucially needed) grey matter than women, whereas women have nearly 10 times the amount of intelligence-related white matter of men.[1]

Grey matter/gray matter
- Discussion moved from User talk:Arcadian
How did you come to the conclusion the latter was the more common spelling? - Mgm|(talk) 10:21, 12 February 2007 (UTC)
- I agree that "Gray" and "Grey" are interchangeable when referring to the color. However, the anon was correct in stating that Gray matter is more commonly used than Grey matter. Both of the online medical dictionary links I can find use "gray": [1], [2]. And two of my three reference books (Netter and BRS/Chung) use "gray" (ironicallly, the one which uses "Grey" is the 2005 edition of "Gray's anatomy for students"). PubMed has 118 hits for "grey matter" and 352 for "gray matter". Currently google usage is roughly equivalent, but I think that much of that is due to mirrors of Wikipedia, which has used the "grey matter" spelling for years. --Arcadian 14:02, 12 February 2007 (UTC)
- Both titles are heavily linked to within Wikipedia itself. Instead of relying on pubmed or Google, I think we should look at what would cause the least redirects. Unless there's a VERY good reason to move it based on whatlinkshere, I think we should leave the article where it is as per WP:MOS (Use the spelling the article was originally created with). - Mgm|(talk) 10:17, 13 February 2007 (UTC)
- Either way, the article should be consistent in that whichever term is used as the redirect target (i.e. the article title itself) should be SOLELY employed in the article text. Tomalak Geret'kal (talk) 00:10, 14 December 2008 (UTC)
- As the guy who has been doing most of the maintenance of neuroscience articles recently, my policy about this is complete indifference. There is a constant low level of people changing between English and American spelling, or changing date formats, and I consider all this far too boring to pay attention to. So as far as I'm concerned you can change this in any way you want to, as long as the links still work. Looie496 (talk) 01:56, 14 December 2008 (UTC)
Presence of Myelin?
According to "Essential Neuroscience," (2007, Siegel et al, page 140) "The gray matter of the spinal cord contains primarily neuronal cell bodies, dendrites, and myelinated and unmyelinated axons..." The introduction to this article makes it sound like gray matter either contains cell bodies exclusively (which is nonsense to anyone knowledgeable about neuroscience) or does not contain any myelinated axons by contrasting it with white matter. (which is much more likely to trip up anyone moderately knowledgeable, as it did me) The wording should be changed to reflect that white matter has a higher concentration of myelin, but that both white and gray matter contain both myelinated and unmyelinated fibers. —Preceding unsigned comment added by Bobsagat (talk • contribs) 01:44, 8 February 2009 (UTC)
- I think you're right -- the wording is not wrong, but is hard to understand. If you would like to take a shot at improving it, please go for it. Looie496 (talk) 17:14, 8 February 2009 (UTC)
- I took a stab at it... I tried to make the changes and keep the sentence structures the same, but I think it's rather awkward. Feel free to clean it up if you wish.Bobsagat 20:39, 8 February 2009 (CST)
Seems contrary
I mean, the title is grey matter but the article uses the spelling gray. 108.6.15.59 (talk) 23:52, 23 February 2010 (UTC)
- One spelling is British, the other American. Every so often people come along and switch them. I long ago decided that it isn't worth worrying about. Regards, Looie496 (talk) 22:24, 24 February 2010 (UTC)
Illustration
The illustration on this page which is labeled micrograph of gray matter is the same illustration on the White Matter page and there is labeled micrograph of white matter. So what gives? Anyone else catch this? — Preceding unsigned comment added by Narjis542003 (talk • contribs) 18:44, 21 September 2011 (UTC)
- The answer is in the image caption: one side of the image shows white, and the other side shows gray. It's not obvious when you first look at the picture, but if you read the caption carefully and then look for what it describes, you'll be able to see what it's talking about. --Tryptofish (talk) 19:35, 21 September 2011 (UTC)
