Scientists Identify Parts of Brain Involved In Dreaming (theguardian.com)
An anonymous reader quotes a report from The Guardian: Scientists have unpicked the regions of the brain involved in dreaming, in a study with significant implications for our understanding of the purpose of dreams and of consciousness itself. What's more, changes in brain activity have been found to offer clues as to what the dream is about. Writing in the journal Nature Neuroscience, Siclari and colleagues from the U.S., Switzerland and Italy, reveal how they carried out a series of experiments involving 46 participants, each of whom had their brain activity recorded while they slept by electroencephalogram (EEG) -- a noninvasive technique that involved placing up to 256 electrodes on the scalp and face to monitor the number and size of brainwaves of different speeds. While the experiments probed different aspects of the puzzle, all involved participants being woken at various points throughout the night and asked to report whether they had been dreaming. If the participants had been dreaming, they were asked how long they thought it had lasted and whether they could remember anything about their dream, such as whether it involved faces, movement or thinking, or whether it was instead a vivid, sensory experience. Analysis of the EEG recording reveal that dreaming was linked to a drop in low-frequency activity in a region at the back of the brain dubbed by the researchers the "posterior cortical hot zone" -- a region that includes visual areas as well as areas involved in integrating the senses. The result held regardless of whether the dream was remembered or not and whether it occurred during REM or non-REM sleep. The researchers also looked at changes in high-frequency activity in the brain, finding that dreaming was linked to an increase in such activity in the so-called "hot zone" during non-REM sleep. Further, the team identified the region of the brain which appears to be important in remembering what a dream was about, finding that this recall was linked to an increase in high-frequency activity towards the front of the brain. A similar pattern of activity was seen in the hot zone and beyond for dreams during REM sleep. The upshot is that dreaming is rooted in the same changes in brain activity regardless of the type of sleep.
I only have the same one, over and over again...
Supposedly everyone dreams, but after 44+ years I have no recollection of ever dreaming. I'd love for them to scan me while I'm sleeping to see if I actually do dream. I suspect I don't, otherwise why wouldn't I ever remember dreaming?
every night.
It operates on the low level activity of the brain, which happens to be experienced as the manifest content of the dream.. bottom up rather than top down, still focusing on areas recently or intermittantly written to. That's my hunch, amyway
Wouldn't it be neat if I could commit the code in my dreams straight to GitHub?
My brother had some mildly traumatic stuff happen in his early teens. My fam wasn't into therapy and he kept having the same troubling dreams. He decided that rather than be tormented he would be on control. Each night he would determine to drift off to sleep peacefully - but he had a plan to remember and also take specific action during the dream. Seemed like he beat it. Long term it seemed like he was remembering all his dreams, and was in a more participatory role. Could all be bullshit, but you could try relaxing before sleep and making an effort to remember. Just a thought, and it is free...
Me too. It keeps telling me that he must die.
Every night I kill me.
A while ago I told myself that if I ever got rich, I'd invest in research into a machine that could record dreams. I'm sure we're still a ways off from achieving this (if it's even possible) but I just really want to be able to rewatch my dreams.
"The result held regardless of whether the dream was remembered or not "
So you are dreaming even if you don't remember it and they cannot prove you were dreaming because this one part of your brain was going off. With logic and rigor like this, we can prove anything!
I'd rather know what my cat is dreaming about than what other people are dreaming about tho.
IMHO, it's for learning from OTHER people's mistakes.
Hypothesis:
1. You witness things done by 3rd person.
2. Some of those things include dangerous and or fatal mistakes and or pleasurable.
3. Your brain replays the days events as though it was you doing it so it can learn from what you saw.
4. You learn not to do fatal and or dangerous thing.
This has a clear evolutionary advantage, each new danger that appears needs to be learned and protected against, and if that danger is fatal, you need to be able to learn from witnessing the danger, experiencing the danger would be too late.
... will I dream?

what other people are dreaming about
As soon as grimfate sells his patented dream recorder to Zuckerberg, Facebook will be able to tell you exactly which other people have been dreaming about you.
Dreams are one of those things you will never understand. They've done similar tests like eight million times, and the theories just get more and more ludicrous.
The wall will include a big beautiful door, so no worries. Now they can dream of crossing the dorr.

When you see her in your dreams, you'll want more.
Keep dreaming. She's been calling you.
Run across those fields and jump over those fences.
They're coming...
And so is she.
Dreams stay with you
Always on my mind, I've got a lust for life
Seasons bring truth
When I found mine, it was summertime
Scientists Identify Parts of Brain Involved In Dreaming. Politicians have welcomed the move as progress towards extinguishing all hope.
All men register for the draft. It's called Selective Service and you have to register or you don't get financial aid to earn that college degree you need to have a chance to suck cock to the top.
The problem with America today is the draft is never called. Pussy ass boys won't protest wars because manipulative politicians realized nobody cares about the wars as long as nobody is at risk of being drafted, so the military industrial complex can do whatever the fuck it wants without complaint.

How do people who are blind from birth dream and does it still involve the visual areas of the brain...?

Simple, it's because you are one of the soulless ones.
Let me guess: more fMRI quackery?
I hate being pedantic, but for a group of intelligent people, slashdot has really been going downhill.
Is this a dream?
In a related study, they also found that this part of the brain starts to quickly decay the day you get your first real job. They also found out that the part of the brain responsible for "hoping" also had the same level of decay.
The racist in this conversation is you. You are the one equating countries other than the U.S. as a prison. The rest of the world is not evil, stupid, and worthless. Your whole disgusting thought process is based in the notion that you are superior and others offer nothing. Not only is this idea absurd, it is harmful. YOU and people like you are the problem in the world.
"Liberalism is a very noble idea, currently controlled by some very bad people. Be sure you do not get the two confused.
Gimme that juicy grant money, y'all !
