Scientists Identify Parts of Brain Involved In Dreaming (theguardian.com) 86
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.

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?

Lucid dreaming, it's a thing and can be fun. You can also remember to count your fingers and or toes (just do it every now and again when you're awake and eventually you should do it when you're dreaming too) you'll almost never have the right number in your dreams, also check the time, clocks don't seem to work too well in dreams. The fingers and toes one works for me. As soon as you know you're dreaming you need to focus on the details like the texture of the floor etc or you might bounce out of the dream

Can confirm -- what worked for me (surprisingly fast) was getting into the habit of checking every now and then whether I'm able to breathe through my nose while I held it closed (obviously do it in a discreet manner at work or wherever). Unfortunately, the first time I actually did this while dreaming, I got so excited about it that I woke up. Took a few more nights for the first actual lucid dream.

Hah. You and I should be teamed up in the study, because we're diametric opposites. I'm 42, and the last time I woke up and *didn't* recall dreaming, I was in high school. If there are times when I'm not dreaming, that would be a surprise.

Dream recall directly correlates with how much zinc and b6 you get in your diet. b6 is water soluble, zinc needs to build up a serum level. Funny thing; cum is high in zinc, and most men on western diets are deficient in zinc. I know in my teens and twenties I put out LOTS of cum on a daily basis, enough to rival most girls monthly periods, yet all the hype about women getting enuf iron never mentions men getting zinc. Try taking 50mgs of b6 and 30mgs of Zn for a week or so. Take them at lunchtime, not just

I do dream but don't remember very many, perhaps 1 or 2 a year. And all but a few in my entire life have been very mundane, dreams about going to work or school. I've read a huge amount of sci-fi, fantasy, comics, historical fiction and haven't had NOT ONE dream about any of it that I can recall.
I have a few dreams, perhaps 1/2 a dozen about flying under my own power, which is very cool but none in the past 25 years.

You know what I an the other way round, I remember dreams as readily as normal everyday memories, no difference. Of course, just like everything I do not remember during normal daily activities much the same with remembering dreams. So what is the most interesting thing I remember from dreams is instances of deja vu. Every time I have an incident of deja vu I can place the dream and the memories that surround it even the segue into and out of the deja vu dream element. So that incident of deja vu is disrup

Memory requires encoding. To remember an event, you need it to go through the prefrontal cortex for interpretation, encoding, and event storage.
