[edit] REM atonia vs Sleep Paralysis
They are not the same, at least in the most current scientific author signed and peer-reviewed literature. Regretfully a web site published anonymously uses different nomenclature. Jclerman 19:02, 19 October 2005 (UTC)
[edit] ?
Don't people also dream in other parts of sleep? I'm sure I've heard this somewhere. Meelar 07:06, 18 Mar 2004 (UTC) Sort of. Most of what you'd call "dreams" when you wake up occur during REM sleep though. Endless
- I read they sometimes occur in Stage 4, but aren't as vivid. They say it might be that its just easier to remember your dreams after waking up from REM sleep. jess523s
There's current discussion on this particular issue. I guess at the moment we can say that REM determines a higher dream-recall rate than Non-REM. Allan Hobson and Mark Solms have held the most significative poles of this debate.
[edit] How rapid?
Does anybody know how rapid the eye movement referred to is?
This varies. Some researches believe it is linked to the level of mental activity, so the more mental activity there is, the faster the REM will be. Darksun 11:53, 4 Aug 2004 (UTC)
Some order of magnitude figures would still be a lot more useful than the current lack of any numerical data on REM in the article. The eye movements in the graph attached to the article appear to be at a frequency of about 1 Hz, but there is no scale provided in the image to indicate amplitude of movement, say as a percentage of possible eye rotation angle. Can anyone contribute any figures like this? I've trawled a few of the archives of research papers I've got access to, but not found anything useful yet.--81.179.145.112 11:29, 24 August 2007 (UTC)
I removed this sentence:
- Studies have shown that being deprived of REM sleep (but not necessarily non-REM sleep) leads to serious mental and physical health problems.
I believe this to be incorrect. Interrupting REM sleep is in fact good for depressed people, and in animals it has been done for some two months without deleterious effects; on the other hand, mice die within 10-20 days if they cannot sleep at all. People have been deprived of REM sleep for a couple of days, and nothing bad happened. AxelBoldt 23:50, 5 Sep 2004 (UTC)
[edit] Cleaned Up
I did my very very best to organize and clean a little.
[edit] Image
I added a poly of a patient in REM sleep. In addition, I added I did a little cleaning. I am concerned about the comment about dreaming though... the one stating that "(whether dreams occur more often during this phase is not known)".... there is every indication that this is the case... The brain activities occurring in stages 2 and 4 sleep are not conducive to the organized thought that takes place in REM. While mentation does occur in NREM, the imagery that takes place in REM is what most people refer to as dreaming. MrSandman 01:06, 26 September 2005 (UTC)
The picture used is not a good example of clear-cut REM as there is a K-complex during the eye movement. In addition to this there is also no scale visible on the EEG.
-
- That is not a K complex.. it is eye movement artifact...which is extremely common. Additionally, the text provided describes the record as being 30 seconds, which is the standard.. and amplitude criterion are not relevant to scoring REM, hence it's absence.
MrSandman 22:45, 19 June 2006 (UTC)
Again, I do agree with the idea that we don't know exactly the nature of the relationship between dream activity and REM. It is possible that REM periods correlate with memory functioning, and not exactly with dream activity. Dream "mentation" or "imagery" is, in my opinion, an artificial distinction from dream activity. --Amoreno22 21:14, 10 July 2007 (UTC)
[edit] Saccadic?
It says REM is 'a saccadic movement of the eye.' Saccade is when your eyes are veiwing a large scene, so does that mean the REM is because your eyes are veiwing a whole picture and your brain is piecing it together. Jess523s 12:54, 24 December 2005 (PST)
[edit] .
The area of your brain that controls eye movements is creating the movements.. it has little to do with what is being "seen" in the dream. It is a bottom up process... not top down.
[edit] REM rebound
I notice there is a brief mention of the role of REM suppression with antidepressants, but I think a section, or better yet, a new page should be created to explain the REM rebound effect that occurs following suppressed REM activity. -Alex
[edit] merger
No merger warranted. Delete the other article. It has no citations to verify the statements which, BTW contradict computational observations. Ask me details if you need them. Jclerman 23:24, 16 May 2006 (UTC)
[edit] REM sleep period
This has not been defined. Please define and insert a citation, or redraft for clarity. Jclerman 07:03, 22 August 2006 (UTC)
[edit] Sleep disorders can occur in REM sleep
Does this mean that the disorders occurs only during REM sleep? Please clarify by recasting the sentence if needed. Jclerman 07:11, 22 August 2006 (UTC)
[edit] REM sleep can occur within about 90 minutes
90 minutes counted from what? Jclerman 07:23, 22 August 2006 (UTC) From sleep onset. MrSandman 17:29, 22 August 2006 (UTC) <edit>... I see what you mean.. that section needs a lot of work.
[edit] no disamb header
Nothing redirects here, so nothing's needed on top of the page... *falls asleep* Matt Yeager ♫ (Talk?) 01:24, 22 December 2006 (UTC)
[edit] Manual Rapid Eye Movement
I am able to rapidly move my eyes in a REM fashion, either with my eyes closed or open, at will. I do not mean that I simply move my eyes back and forth rapidly, but rather that my eyes do it "on their own." I know of at least one other person who can manually induce REM as well, so I imagine the ability to manually control rapid eye movement is somewhat common.
The article is not titled "Rapid Eye Movement Sleep Phase", but rather just "Rapid Eye Movement." Should mention be briefly made that some people are able to manually induce the rapid eye movement which occurs in REM sleep? Serialized 12:19, 29 December 2006 (UTC)
I have a question: Why exactly does REM the activity accompany the REM state of sleep? What's the point of moving our eyes so quickly? Is it a part of looking around in the dream or just something weird we do? Why are the eyes the one part of the body not paralyzed in sleep? 66.91.214.167
Moving your eyes does not induce REM. Read the article for more information, specifically.... pay attention to the brain-stem mechanisms that modulate REM sleep.
[edit] Added see also to Dream article
I recently added a bunch of information about the brain while dreaming to the Dream article, I noticed it overlapped quite a bit with what happens during REM since dreaming usually occurs during REM, some of the info is really more about REM Sleep than dreaming, do you think we should add it here instead of the Dream article?

[edit] What if you don't have eyes
what if you're blind or you're missing your eyes or something. can you still experience this stage? the mental effects at least? —The preceding unsigned comment was added by 70.59.5.156 (talk) 15:52, 14 March 2007 (UTC).
How would you make this difference: Mental effects vs... Organic effects? The REM does not have a perceptive function. --Amoreno22 21:17, 10 July 2007 (UTC)
The eye movements are a product of what the brain is doing.. eyes or no eyes.. the brain experiences REM sleep... just like a baby does before they are born. The article explains some of this.

[edit] Rapid eye movements related to eye movement in dreams?
Lucid_Dream#Other_associated_phenomena makes the assertion that "Scientific research has found that these eye movements correspond to the direction in which the dreamer is "looking" in his/her dreamscape; this apparently enabled trained lucid dreamers to communicate the content of their dreams as they were happening to researchers by using eye movement signals. This research produced various results, such as that events in dreams take place in real time rather than going by in a flash." While it is certainly true that lucid dreamers can give preconcerted eye signals while dreaming, I did not yet find proof for the assertion that REM is generally linked to the eye movements of the dreamer or even the lucid dreamer (I think you would need dream reports corresponding to eye activity for that, which would be somewhat hard to create). It would also be in contradiction to the fact that "events in dreams take place in real time rather than going by in a flash", because we don't move our eyes rapidly in real time.
However, I think the false idea should be mentioned in the article, because the topic seems contentious and at least two people asked about this correspondence on this talk page.--Ruben 22:03, 1 December 2007 (UTC)
[edit] Why the title "REM sleep in other animals"?
I don't understand why the sub-title is not "REM sleep in animals" - "other animals" implies that human beings are a sub-species of animals. I am not changing the sub-title as I do not want to get into fights, but I really think it's rather strange. Thanks - Todd (talk) 12:11, 9 December 2007 (UTC)
- No "-sub", just one of the many species. Jclerman (talk) 22:31, 27 January 2008 (UTC)
- Humans are animals the same way we aren't vegetables or minerals. Like other animals, we have guts, feet, hearts, skin, blood, and apparently, dreams. Completely correct. —Preceding unsigned comment added by 67.167.248.233 (talk) 01:32, 27 January 2008 (UTC)
[edit] Pronunciation
What is the correct way to refer to REM in talking? Is it R-E-M, or rem? Could somebody who knows include this in the article? —Preceding unsigned comment added by 89.125.36.15 (talk) 10:06, 5 February 2008 (UTC)
