"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.

[edit] 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]

[edit] 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)
