invisiblebrain Posted May 31, 2004 Author Share Posted May 31, 2004 that was the point i wanted to bring out in the topic.... REM sleep is the most fascinating part of it and i belive it dominates the non-REM whcih is justa transition period. so if we dont sleep for rest ,why then do we have to sleep in the first place?

admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 no, but the idea is that you need the non-rem sleep to take you into the rem sleep. if i recall correctly, there have been several experiments where people were simply not allowed to have rem sleep and as a result they had behavioral/concentration problems when awake.

Crash Posted May 31, 2004 Share Posted May 31, 2004 Whats REM sleep?, i thought you sleept to rest your body, but not your mind Link to comment Share on other sites More sharing options...
admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 REM = Rapid Eye Momement cycle. a typical sleep is in cycles(forgot the fine details) but more or less it goes in stages. Rem sleep is where most dreams occur - and as my above post said, it has some kind of correlation to the overall function of the brain. when you hit rem stage, when you wake up, you feel refreshed and had a dream, and in sleep, your brain is just as active when you're awake, maybe more so. that's why if you've ever had one of those occasions where you've only slept for 20 minutes and feel so much better/refreshed then say last night when you slept 12 hours and woke up feeling tired and moody. etc. more than likely, in the above example, you've bypassed all the other stages of sleep and went directly into rem...

invisiblebrain Posted May 31, 2004 Author Share Posted May 31, 2004 ask any teenager ,one says he had sexual arousal in the sleep.so what does that suggest? does that sugget that the sleep we are in does help us to prepare ourselves for the future occaisions of sex or for that matter any of the lifes problems???

admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 ask any teenager ' date='one says he had sexual arousal in the sleep.so what does that suggest?[/quote'] well, the penis erections and vaginal lubrications seem to be a common thing during rem sleep does that sugget that the sleep we are in does help us to prepare ourselves for the future occaisions of sex or for that matter any of the lifes problems??? don't know. but probably that's an overstatement. it's not age specific or confined, rather.

Crash Posted May 31, 2004 Share Posted May 31, 2004 Well with all the theorys about Dreams being connected to your life in some way, im sure that they are....but just how is weird. It could be as you said "help us to prepare ourselves for the future occaisions of sex or for that matter any of the lifes problems??? Or could just be a way of your subconcious trying to tell you soemthing...on that note my girlrfeind has had some weird dreams,(One was about another guy, in which she dated in her dream which made me worry!!) now i really want to know what they mean???? Why dont pot smokers dream as much as non-smokers? for me when i use to smoke (rather reguarly)pot i never can remember dreaming, now i can atleast remember my dreams though..

admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 No im quite sure i do want to know, is it cause of the damage it does to your brain? no. i take it you did not read my last post in that marijuana thread, did you? smoking marijuana does not cause brain damage, but it slows it down. as the article or linky says, in some cases, even the heavy or prolonged use of it can be reversed. the problem with marijuana smokers would be their difficulties in recalling memories or concentration, etc. rem sleep is more or less in real time. meaning if you've just had a rem sleep for 20 minutes, and right at the end, someone woke you up, you can probably recall (from memories) what you've just dreamt about and be able to talk about it for up to 20 minutes. but the longer the time has past since your last rem cycle, the less things you can remember from it.

admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 oh yeah, the other part of your question, brain is very complicated and hard to understand - aka pandora's box. it might actually be the case that we'll be able to decipher all of genome and be able to control it at will, before we can do the same for the brain. it's just That complicated.

Crash Posted May 31, 2004 Share Posted May 31, 2004 Sleep must be atleast something to do with tiredness as you sleep alot better after exercise than yu do after a boring day...... And this may seem stupid or obvious, but why do you get to sleep alot better when drunk or under some sort of influence? Link to comment Share on other sites More sharing options...
admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 it has to to with the passage or blockage of ions at the synaptic cleft. it kind of works like a "key and lock" or "hand and glove" thing as they say. the molecule found is alcohol let's say looks like a triangle. when these molecules flow around in the brains, if there's a trianglular shape found at the neuron that this alcohol molecule could slide in, then it will. once it's in, it will block the passage of the other molecules that are normaly produced by the brain, then it can influence the neuronal activity/behavior, at least for a while. sorry, i'm a little vague and rough on details Link to comment Share on other sites More sharing options...
admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 if you're more into biology, it pretty much works very similarly as in biology and gene transcription and the uses of lactose molecules, operons and active/inactive repressors that bind or not to a piece of genetic segment. -the above is how bacteria does it - human transcription process is a bit more complicated, but very similar Link to comment Share on other sites More sharing options...

invisiblebrain Posted June 1, 2004 Author Share Posted June 1, 2004 oh another way i like games ,some FPS ones too(wolfenstein,igi,hitman......)whwre the way is complicatd and one has to find it out . it happened so many tmes to me that i couldnt go to the door and frustrated myself. after i slept i remenber scanning through all the ways and seemed to correlate which way i had to go and most of the times i would find the door or key then. same things with some math problems. now what do you say?

So at the end of the day when you feel all crapped out or whatever, you just sleep and removes all that. I know when I've been in a mad/frustrated mood and went to bed, but only to have restless sleep, I wake up with the exact same madness/frustration as when I went to bed. When usually it would be a completely different day. Sleep is an orginization time for the brain I think, just cleaning stuff up so it can funtion well the next day.

admiral_ju00 Posted June 3, 2004 Share Posted June 3, 2004 Since this bears relevance to this discussion: It is a common belief that we are more susceptible to infections when deprived of sleep. Consistent with this, there is increasing evidence that sleep deprivation has detrimental effects on the immune response, indicating that sleep should be considered a vital part of the immune system and that there is a reciprocal relationship between sleep and immunity. This relationship is important because, over recent decades, there has been a documented decrease in the mean duration and quality of sleep in the population. The concept that lack of sleep might be compromising immunity in the population has far-reaching public-health implications for both individuals and society. Sleep-deprivation experiments in both animals and humans provide the best evidence for a crucial role of sleep in the immune response. The results of these experiments show some inconsistencies, thereby underlining the complexities of measuring the interaction between different durations of sleep deprivation and different immune components. However, in humans, general patterns emerge, indicating that sleep deprivation has detrimental effects on immune-cell number, function and cytokine production. There is also emerging evidence that chronic partial sleep loss might be more detrimental to immune function than short-term total sleep loss. This is important because it is chronic partial sleep loss that burdens the current population, through shift work, pressured lifestyles, and other stresses and changes in society. The final piece of evidence for a reciprocal relationship between sleep and immunity is provided by clinical situations (for example, depression or narcolepsy) in which sleep disorders are associated with changes in the immune system. The effects of sleep deprivation on the immune response might have important implications for protecting the population against infection and malignancy.

qazibasit Posted July 3, 2004 Share Posted July 3, 2004 there are different states of sleep which we called different brain states and we can see it with the help of EEG , i dont know of which state you are talking but defferent states have different significance for example in delta state we die for about few microseconds and our physiology is totally stopped, just like a supercomputer computer is turned off for a few seconds and this is enough to give rest to the brain and in other states the worn out cells are replaced in the body and other wear and tear is done.
