Talk:Pineal gland

Blood Pressure
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

Fluoride
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.

Sorry, but this is not scientific - if "the contrary exists" - well then - we look forward to the sources? where are they? — Preceding unsigned comment added by 80.108.129.198 (talk) 20:48, 28 March 2021 (UTC)

footnote [7] wrong?
In footnote [7], the referenced article doesn't seem to discuss "A few more developed vertebrates have lost pineal glands over the course of their evolution" like the statement states. Correction needed here I think! See, "A few more developed vertebrates have lost pineal glands over the course of their evolution.[7]".

If I am wrong or you find the correct article indicated what the statement says, I would love to hear about it. — Preceding unsigned comment added by 73.153.146.226 (talk) 02:29, 26 July 2020 (UTC)

Descartes mind/body diagram
Why is Descartes mind/body diagram on this page? He was wrong about the function of the Pineal gland, and the diagram does not depict the operation of the pineal gland like the caption says. — Preceding unsigned comment added by 71.84.127.250 (talk) 21:10, 26 October 2020 (UTC)
 * The image - a famous one among neuroscientists and neuroanatomists - is displayed in the Society and culture section where the true pineal function and structure are not intended to be defined as we understand them in the 21st century - the main article sections adequately represent them. Here's a 2020 view published in Neurology. There is some historical significance to the image, showing it had the attention of people studying the brain nearly 400 years ago.
