This page doesn’t mention what species have a Pineal gland.—GJK 10:33, 19 October 2005 (UTC)[reply]

I have no idea what Gray's Anatomy means by "animal matter" in the second paragraph of the structure and composition section. -- Phyzome is Tim McCormack 22:44, 2004 Dec 8 (UTC)

I think the animal matter refers to a complex of proteins. The associated anatomical structure is really peripherial. I guess removing it should be the best for the article... moostattack

I think this article is in desperate need of images. The description of where this important gland sounds like ancient Greek to someone that knows nothing about the brain and it's anatomy. JoeHenzi 18:40, 5 Apr 2005 (UTC)

The third paragraph under "Functions" starts with, 'It also contains a substance which if injected intravenously causes fall of blood-pressure.' Is this supposed to refer to the correlation between blood pressure and Melatonin production?

The description in "Functions" is vague. Melatonin usally increases potassium channel conductance thereby slowing down the heart rate and possibly relaxing the endothelium (haven't checked this). moosattack

I have a cyst on my pineal gland is that dangerous? Does this have anything to do with balance?

I read this at http://www.chm.bris.ac.uk/motm/serotonin/introduction.htm

Is that true? If so, shouldn't it be added so it says it produces 'melatonin' and 'serotonin'. I believe the endocrine system would need to be edited too.

What causes the pineal gland to calcify and is there any possible connection between the pineal gland and diabetes ?

While I've heard this in every neuroanatomy class I've taken, I've never seen a reference given. After some searching, it appear it's from Descartes' Treatise of Man. Note I haven't checked this myself yet, but I found that information here: http://plato.stanford.edu/entries/pineal-gland/#2 Semiconscious (talk · home) 20:04, 28 December 2005 (UTC)[reply]

There is no reputable evidence that fluoride has any influence on humman sexual maturity. In fact, the contrary exists. So, let's just drop this line in the article until peer-reviewed data is available.

Hi, I just want to emphasize the following viewpoint. I understand Wikipedia aims to be encyclopedic and present all sides of an issue, but we need to prevent pseudoscience from discoloring all of our articles, including this one. Some of the previous edits have made strong claims about the psycho-mystical third eye and pineal gland connection. While we should mention this as a historic or philosophical angle, the best way to present this is in a clearly labeled sub-heading, such as "Philosophy" or "Mysticism." This will help prevent people from confusing science and medical fact from religious or new-age ideas.
