Cleaned

Cleaned it up a bit and added figures of stages 1, 2, and 4.

Induction and cycles

Can someone add something about the VLPO/Histamine blockade in the hypothalamus as well as other structures involved in induction? Also representation of number of cycles and description of length (with the obviously associated graph) would be helpful. Thanks. 128.104.132.80 04:49, 18 June 2007 (UTC)

Merge

has been suggested. I agree that SWS should be merged into NREM, not the other way 'round, as SWS is a part of NREM. --Hordaland (talk) 06:38, 24 May 2008 (UTC)

Don't merge - I found the Slow-wave sleep (SWS) article as I was looking for deep sleep. It seems that the current SWS has detail, such as the affects of various dugs on SWS, that would not be appropriate for the more general NREM article. Marc Kupper (talk) (contribs) 19:13, 6 July 2008 (UTC)

So, are we merging it? - It's been over a year, so it looks like it might be time to either remove the tag or merge it. Ertemplin (talk) 15:02, 2 June 2009 (UTC)

Comment Tough call. I agree with Hordaland that merging NREM into SWS makes zero sense. However, SWS itself has an ever expanding body of literature and interest in regard to its functions in sleep, pharmaceutical limiting effects of it, associated parasomnias, and daytime symptomology from its deprivation. It may very well be worthy of its own article but could probably be the bulk of the NREM article with a deep sleep/SWS redirect. A real question might be is NREM worthy of its own article without a full discussion of SWS included--unless you wish to just carry on about slow rolling eye movements and spindles? :) Cronides2 (talk) 17:29, 12 October 2009 (UTC)

Just to muddy the waters, here's another thought. We have no article entitled "Stages of sleep" nor "Sleep stages"; they are both redirects to Sleep, now 62 kilobytes.

Might we consider a Sleep stages article? It would include

• the section from Sleep, which now includes sub-sections on REM and NREM,
• Rapid eye movement sleep which has 23 refs and a tag saying that it needs citations,
• Non-rapid eye movement sleep (tagged for additional citations),
• Slow-wave sleep (tagged for refs/sources), and
• a decent history of what-knowledge-when.

These mostly refer to one another, changes to the one aren't reflected in the next. Possibly some of the (more technical) stuff about Polysomnography could be moved to that article. Speculation on the use and purpose of sleep and its stages should IMO be kept to a minimum; we know actually little, and people are tempted to add the most recent studies in flies and rats.

These are thoughts I've played with for a year or more. But it looks like tooooo big a project. And I'm only interested, not qualified. - Hordaland (talk) 21:26, 12 October 2009 (UTC)

Sounds hard. I say just merge. onyx³²¹ 09:51, 28 April 2011 (UTC)

This is a stolen, copywrighted article

I read the same article verbatim on answers dot com. Same pictures and everything. I'm too lazy to do it but if you want sources they should have some.

It's not stolen, in either direction. Wikipedia content is free, and anyone may use it. Such content is often found on other websites without attribution. However, in this case, you just didn't scroll down far enough. Near the bottom of that answers.com page it says: This entry is from Wikipedia, the leading user-contributed encyclopedia. It may not have been reviewed by professional editors (see full disclaimer)

Disjointed Article missing section on "Possible Purposes and Function of Slow-Wave sleep"

This article lacks coherent information on the possible biological function of slow-wave sleep (both neurological and physical), for instance the possible role slow-wave sleep plays on declarative memory or the role slow wave sleep may play on physiological processes such as (anabolic processes) healing, growth, growth hormone production, and catabolic processes. As well as the potentially severe physical and neurological harm that can occur from the deprivation of this stage of sleep (as opposed to the impact of.... say REM sleep of stage N2 of NREM sleep). —Preceding unsigned comment added by 66.130.154.212 (talk) 16:32, 23 March 2009 (UTC)

Dreaming during Non-REM

The introduction states dreaming during non-REM sleep is "rare" which I question. There are a lot of newer studies that show many dream during non-REM sleep, but they are different types of dreams, and not as long. I would prefer a professional to elaborate on this though. —Preceding unsigned comment added by Leckey76 (talk • contribs) 03:54, 29 November 2009 (UTC)

Thank you for making the above comment - I wast just thinking of typing something similar myself! My point was going to be that although it is popularly - and fallaciously - believed that dreaming only takes place during REM sleep, there is some evidence that dreams do take place in NREM sleep (they appear to be qualitatively different, however, to those during REM sleep, being much more logical than dreams in REM sleep).

Added reference

I added a reference to an article from the National Institute of Neurological Disorders and Stroke regarding hypnic jerks. Cbarlog (talk) 00:03, 22 February 2012 (UTC)

Some suggestions

The lead section needs to be rewritten; there are unimportant facts included that make it too hard to follow. Maybe put those in a different section.

Also, the structure is a little random. Maybe write it so that the most important sections are first, which those smaller details as sub-sections.

Finally, it feels a little unbalanced. There is so much on SWS, but not much on polysomnography and dreaming in NREM. More could probably be added about the stages of NREM as well. I'm also curious as to why muscle movements in NREM was it's own section, instead of a subsection on sleep disorders associated with NREM sleep.

These are just friendly suggestions for improvement; not trying to step on anyone's toes! Cloontj2 (talk) 14:43, 28 March 2014 (UTC)

Dreaming in NREM section

The first part of that section seems to be talking about REM, and not NREM, and it seems very trivial to this page as a whole. I think it should be removed, because it just causes confusion. Thoughts? Cloontj2 (talk) 19:54, 28 April 2014 (UTC)

Well, the discovery of dreaming in NREM-sleep is relatively new and not well-known. I think it does belong in the article. However the present section is confusing and poorly written. --Hordaland (talk) 20:50, 28 April 2014 (UTC)

I agree with you there, dreaming in NREM is an important part of this page. As for the part that needs to be removed, I just meant the first sentence. It talks about REM instead of NREM. Cloontj2 (talk) 16:21, 5 May 2014 (UTC)

Opposed to Non-REM

I couldn't find a style guide that deals with this. Weirdly, NREM itself is halfway between an initialism and an acronym (at least as I pronounce it: en rem). The phrase is not normally capitalized, so it seems odd (and a bit garish) to me to see Non-REM instead of non-REM. But I did see "Non-REM" used at least once in Nature, so I restrained myself from changing this usage in the article.

I can see no grammatical precedent for a lower case word becoming an upper case initial, then reverting to an upper case word, though perhaps somewhere out there there's a reference stating that partial de-initonymization actually works this way. — MaxEnt 02:34, 28 February 2017 (UTC)

VCAA Incorrect information.

While it was true that VCAA taught NREM stages 1-4 in the curriculum, from this year onwards it has been changed to NREM stages 1-3. Ab3503 (talk) 10:28, 12 July 2023 (UTC)

@Ab3503: I've removed the statement from the article. Thanks for raising the matter. JBW (talk) 10:45, 12 July 2023 (UTC)
