Talk:Rapid eye movement sleep

message: In the introduction you mention that there are two categories of REM sleep: tonic and phasic. I think this article could be improved by adding information about both of those phases since after in introduction they are not mentioned again.

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. 
----
Mark Solms claims that there is no difference in dream quality between REM and NREM sleep. Most studies however have shown that when you wake a person up from REM sleep you get a dream report 80-90 percent of time where this is only 10 % for when you wake a person up from NREM sleep. However, as mentioned before it could be the case that it is harder to remember a dream in REM sleep. Some have also argued that you only dream in REM sleep and dream reports from NREM awakenings are just memories of dreams that happened in NREM sleep. This is dubious however since Solms showed that people who have neural damage to the degree that they don't have REM sleep anymore still dream.  — Preceding unsigned comment added by 130.235.159.180 (talk) 11:31, 5 December 2011 (UTC)

Yes. Every three seconds: http://lsdbase.wordpress.com. And please feel free to update the image in the article with a more modern recording while you are there.  — Preceding unsigned comment added by 203.9.185.137 (talk) 23:43, 21 September 2011 (UTC)
replies: text: In my experience, its usually no more than 4 notable eye movements per epoch (30 seconds), and there can be full epochs of REM EEG activity but with no eye movements. 173.71.95.164 (talk) 14:10, 14 November 2009 (UTC)

text: 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)

text: Yes, nothing bad happens to someone deprived of REM sleep for a couple days. Consistent REM sleep deprivation causes a deterioration of cognitive function and, well, a lot of other bad things, too many to list. 173.71.95.164 (talk) 14:24, 14 November 2009 (UTC)
thread_title:  How rapid? 

message: 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.

replies: text:  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.

message: 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)

thread_title:  What if you don't have eyes 

message: 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)

message: 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.

message: At the beginning of the first paragraph there is a brief mention of REM being divided into two phases, Tonic and Phasic.
This is not elaborated on anywhere else in the article, and the citation is too a book rather than a website.
Maybe there should be either more information added to that, or else it be removed.

replies: text: They aren't necessarily distinguishably separate phases, but separate aspects of REM stage sleep with variables pertaining to neurological, cardiovascular, and respiratory rates/statuses. As a polysomnographic technician, this was not something I was initially trained to distinguish, but the fact that REM is "tonic and phasic" was brought up quite a lot. I suppose it's something the doctors know more about, and is probably a necessary statistic for diagnosing more complex sleep disorders... something like that. In any case, it is relevant to define REM as being tonic and phasic, but explaining it would probably require a couple paragraphs of its own section within the article.  —Preceding unsigned comment added by 173.71.95.164 (talk) 13:54, 14 November 2009 (UTC)

message: The introduction of this page and Delta wave page claim different things:
* A newborn baby spends more than 80% of total sleep time in REM.
* Infants have been shown to spend a great deal of time in slow-wave sleep, and thus have more delta wave activity. In fact, delta-waves are the predominant wave forms of infants. Analysis of the waking EEG of a newborn infant indicates that delta wave activity is predominant in that age, and still appears in a waking EEG of five-year-olds. 
This definitely needs looking at. --Melarish (talk) 13:21, 28 December 2011 (UTC)

message: I think this article could benefit from some mention of the link between  reduced REM sleep and pain.  e.g. studies have shown possible links between chronic musculoskeletal pain (incl fybromyalgia) and reduced REM sleep.  Experiments have been conducted wherein individuals were deprived of REM sleep; a proportion of these individuals developed fybromyalgia-like symptoms.  REM sleep is often noted to be poor in people recovering from surgery, but normalisaton of sleep occurs as recovery proceeds. Splodger101 (talk) 00:14, 22 December 2012 (UTC)
