    Japan scientists can 'read' dreams: study

    Scientists in Japan said today they had found a way to 'read' people's dreams, using MRI scanners to unlock some of the secrets of the unconscious mind.

    Researchers have managed what they said was "the world's first decoding" of night-time visions, the subject of centuries of speculation that have captivated humanity since ancient times.

    In the study, published in the journal Science, scientists at the ATR Computational Neuroscience Laboratories, in Kyoto, western Japan, used magnetic resonance imaging (MRI) scans to locate exactly which part of the brain was active during the first moments of sleep.

    They then woke up the dreamer and asked him or her what images they had seen, a process that was repeated 200 times.

    These answers were compared with the brain maps that had been produced by the MRI scanner.

    Researchers were then able to predict what images the volunteers had seen with a 60 per cent accuracy rate, rising to more than 70 per cent with around 15 specific items including men, words and books, they said.

    "We have concluded that we successfully decoded some kinds of dreams with a distinctively high success rate," said Yukiyasu Kamitani, a senior researcher at the laboratories and head of the study team.

    "I believe it was a key step towards reading dreams more precisely," Kamitani told AFP. (AFP) IKA BOD 04051210

    This is a bit hyped. this is something that was already being done for a long time. The basic idea is very simple, they take pictures of their MRI scans live, while asking them about various things. And take a picture of their brain scans for every thing that they asked. later they tell the person to think about the things that they talked and checks if he images have in their hand pop up in the MRI scanning display. If they get a match, that mean they're thinking about the thing that they have an image of in their hand.

    This is old science. The new science is based on brain neural network mapping, which works to predict intelligently about what is going on in the brain. No breakthroughs yet on this fron though. The new initiative called BRAIN by the US govt. has alot to do with this. Although something tells me that that's not a good thing. Since the US govt. will probably only abuse their research findings.

    When they say read dreams, do they really just mean read thoughts?
    What makes waking thoughts intrinsically different in their physiologic manifestation in brain from dreams?
    Like, if I were thinking hard about eating a sandwich, they'd be able to read that too right? This opens a whole new world of potential in terms of lie detection technology. Soon we will not even be safe in our thoughts! 0_o

    It doesn't mean either. It's just the media misquoting coz they don't know the technicality or to create sensation.

    What they actually mean is, we can read brain activity. And compare the activity with a database of MRI scan pictures to find a match.
    Each MRI scan will have a tag attached to it, like when it was taken or what the subject was doing when it was taken, or what the subject was told to think about when it was taken.

    If they get a match, then they just have to check the tag behind the match they found. And if the match has a tag called, say, banana, then you can conclude that they the subject is thinking about banana.

    Yes it opens up possibilities in lie detection. Although it's a bit crude technology, since you need an infinitely large database to make sense of the complexity of human thought. Right now all it can do is, do match making.

    To answer your question, yes, it can read your dreams, since dreams are brain activity. Whether you are up or sleeping doesn't make a difference since brain activity happens at both times.

    You can see a basic version of this technology being used in real life, like the wheel chair which physically disabled American scientist Stephen Hawking uses, which recognizes small electric signals that his brain makes and compare them with a database of pre-recorded elctric signal pattern to choose commands like 'turn', 'drink water', 'move forward', etc.

    In MRI scan matching, it just compares pictures of the brain instead of comparing electric signal patterns generated by the brain.
