Some scientist at UC Berkeley have managed to pull off something awesome: record visual brain activity into video! Scientists Reconstruct Brains? Visions Into Digital Video In Historic Experiment UC Berkeley scientists have developed a system to capture visual activity in human brains and reconstruct it as digital video clips. Eventually, this process will allow you to record and reconstruct your own dreams on a computer screen. I just can't believe this is happening for real, but according to Professor Jack Gallant?UC Berkeley neuroscientist and coauthor of the research published today in the journal Current Biology?"this is a major leap toward reconstructing internal imagery. We are opening a window into the movies in our minds." Indeed, it's mindblowing. I'm simultaneously excited and terrified. This is how it works: They used three different subjects for the experiments?incidentally, they were part of the research team because it requires being inside a functional Magnetic Resonance Imaging system for hours at a time. The subjects were exposed to two different groups of Hollywood movie trailers as the fMRI system recorded the brain's blood flow through their brains' visual cortex. The readings were fed into a computer program in which they were divided into three-dimensional pixels units called voxels (volumetric pixels). This process effectively decodes the brain signals generated by moving pictures, connecting the shape and motion information from the movies to specific brain actions. As the sessions progressed, the computer learned more and more about how the visual activity presented on the screen corresponded to the brain activity. Source: Gizmodo (http://gizmodo.com/5843117/scientists-reconstruct-video-clips-from-brain-activity) Don't know what they're talking about? It's basically just a scanner picking up your brain activity while you're watching their movie and it converts your brain activity into a video. They use 18 million seconds of random YouTube videos in order to display the final product, which is basically a mash-up of all the videos the system they're using filtered out through your brain activity. In other words, your brain activity is the filter. http://www.youtube.com/watch?v=nsjDnYxJ0bo I'm definitely excited about this! First the speed of light theory is being tested, and now this! Two awesome scientific news discoveries in a row (in this week)!

This is awesome, but I'm afraid that I won't have the freedom of thinking in a few years. WHAT WILL THEY TAKE NEXT???

I thought i remember hearing something from Japan couple years back of a similar dream recorder, don't remember the link but it involved pictures of letters or something like that. I really don't think seeing what others dream of is a good idea, since dreams can get pretty weird and creepy :eek: FYI: I haven't been able to remember my dreams for the past 5 years or so idk what i dream of And I really don't think i want to use this to find out :eek:

Wow, I am personally more excited than terrified. o: I guess I am just curious to see my dreams replayed to see how accurate my memory is, and the whole concept is really interesting. (Although they are mostly meaningless and bizarre mash-ups of everyday life, I remember dreams quite frequently, but they are not up to much.) I don't think I would mind seeing nightmares either, because its more the feeling and tone of the dream that scares me, rather than the actual 'visuals'. But I wouldn't want others to see what randomness goes on inside my head.

This is definitely very cool. I personally can't wait to see what kinds of neat things they do with this technology. There sure have been a lot of big scientific breakthroughs recently, haven't there? Between this, the discovery of neutrinos travelling faster than the speed of light, and Euclidian's Infinite Detail graphics engine, the future is looking pretty bright.

Just in case you don't know, sometimes dreams actually help contribute to new ideas. I watched a show like about a year or two ago about a NASA employee who helped design one of the moonwalkers based on a dream of his. Imagine of all the new ideas can come out of seeing our own dreams. Imma make my dream an animated series.

Not quite a dream recorder though; This is the first rudimentary steps into fully understanding how the human brain processes visual information - and recreating it. I reckon a similar trick could be performed to recreate a noise based on the brains response to external sounds. But at the same low resolution reproduction as those videos, the sounds would be pretty much indecipherable. I mean, if you were to see just the reproduced images (and not have the originals for comparison) - I doubt many people would be able to decipher the images accurately. As dreams are imaginary (a construct of the subconscious mind) and not fed externally through a job-specific sensory organ (like an ear or eye) - the possibility of deciphering the brains subconscious activity into anything even remotely recognisable (even by the person who had the dream 1st hand) - is still a LONG way off (if it will ever be possible at all). Still a very cool trick though

Imagine the wonders this tech could do to this ol' thread (https://lbpcentral.lbp-hub.com/index.php?t=18049-What-Did-You-Dream-About-Last-Night) of mine! *Wink, wink. Nudge, nudge. Bump, bump.*

Well yes, that should be common sense. The amazing thing though is that they actually produced video by only using brain activity. It's pretty interesting and I won't be surprised to see it evolve into something like an actual dream recorder. After inventing so many things and making so many discoveries (like the AIDs enzyme breakthrough) I give up on doubting possibilities.

I can see other (more useful) applications for this technology than recording/recreating peoples nonsensical dreams. If they were to fully understand the mechanism by which the brain processes images, it opens up the possibility for "enhanced" vision - think a HUD style brain augmentation that we have seen postulated in many video games/scifi. - Imagine having access to google direct from your brain But aswell as all of the other information that google have on you - imagine if they also had access to everything that you look at through-out the course of a day.... it's a marketing executives wet dream.

Now only if that can be used as useful tool if science can prove that human can predict the future with dreams.. I smell Minority Report.. or it's just my delicious pepperoni pizza in the oven.

*Gulp* Better stop dreaming! Or I may be considered a weird person, having seen my dreams. Wait? Isnt a dream just product of what you are thinking in the mind at one certain point? So that means to dream a weird dream I would have to have thought about it. *Gulp*

A dream recorder?!?!?! Awesome!! If only they were sold in stores. That would cost a fortune. Something like this. Dream Recorder $1,000,000,000. Too much?

Of course, this technology only works by building a composite image from youtube footage. So if it was to recreate your dreams, there would need to be enough similar images also uploaded to you tube to build the composite image. And judging by the stuff I dream about, I doubt you tube would have those kinds of videos.... in fact, I know they don't.... I've looked

while i like the idea of going into my mind and picking out a dream to show people, this technology so far wont be able to recreate a lot of dreams out there...not everybody dreams about things youd expect to see all over the place all the time but, if they go as far as to actually seeing what you see and showing it on a screen or something....it would be useful for getting your dreams out there, but ONLY if an individual can pick out and choose what they show from their own mind....i dont want people, looking into my mind and stealing my ideas for things, stealing my passwords and information i remembered, looking at thoughts i dont want them too and taking away my privacy in my thoughts. you have things inside your mind that can be used against you in a compromising fashion, and to me its a bad thing if people start being able to mind read other people. which is why, id prefer to pick and choose my dreams and thoughts to show people by myself....and it would only be my dreams that i carefully choose id like it where people cant mind read you, like at all...but you can mind read yourself, and show a select set of thoughts/dreams...that way, nobody can see information that you dont want them too. and if you dont want them to see anything? then dont use the machine, which in retrospect would probably be the wisest thing to do. to bad the human race is hellbent on screwing other people over... i can see its uses and why it would be a good thing, but i can also see its disadvantages and why it would be a bad thing...but all in all, its probably the best thing NOT to do it....but you know...eventually we will anyway, bad. of all the good things you can think of to make use of it...they wont, theyll just use it to manipulate people...

I know how they'd end up using it.... "This Dream was brought to you by Coca Cola"

I feel both excited, and worried at the same time. Excited: many of my dreams have been highly amusing in their weirdness (I have scared elite MGS soldiers out of their minds, blabbered about random things with Captain Qwark, and also flied at insane heights with breakneck speed; oh, and also sliced to small pieces by ninjas ). I'd love to have a near-perfect visual replay of that. And worried: many of my dreams also contain content which is highly personal, and could be extremely damaging if revealed. I can now cope with that, since I can easily censor my dream diary (e.g: omitting certain subjects/dreams altogether) if so desired. It would be much harder with a dream recorder, since it would record *everything*. I'd never let one to be used on me, unless I (and only I) get to decide about the output resulting.

Yeah, that's how I more or less feel about it.
