I was wrong. THIS is the best thing Experimental Vibrational Analysis for Hire.

Visual Image Reconstruction from Human Brain Activity using a Combination of Multiscale Local Image Decoders

I'll make this as simple as I can for you.

This is the image that the subject looked at.
v

And this is the image that Now Yukiyasu Kamitani at ATR Computational Neuroscience Laboratories in Kyoto, Japan, directly extracted from the subject's brain via an MRI scan.


Yes, ladies and gentlemen. Mind reading has become a reality for 21st Century Earth.

This is the first "mind-reading" technology that can create images from scratch rather than picking it out of a selection of prepared images.

Earlier this year Jack Gallant and his colleagues at the university of California showed that they could tell which of a set of images someone was looking at from a brain scan. They did this by developing software that compared the subject's brain activity while looking at training photographs.

But Yukiyasu Kamitani's breakthrough actually puts together an image using the data from the brain scans themselves. Kamitani: "By analysing the brain signals when someone is seeing an image, we can reconstruct that image."

At the moment, the resolution of the output and sensitivity of the instruments means that only simple, contrasting images can be read. They do this by making the subject look at several 10/10 squares while having their brain scanned. The new software finds the brain activity that corresponds to each pixel being blacked out.

Then, when the test image is used, such as the word "neuron" above, the software compares the brain activity observed with the catalogue of data from that subject's brain. The results, as you see above, are the proof of concept.

As fMRI technology improves, the resolution could be increased substantially. The next step is to see if it is possible to image things people are thinking of as well as looking at. Dream videos, anyone?

Not of mine, though, God no. I wouldn't subject you to that. Or myself to the courts.

Shit that is pretty cool.

This is not so shocking. Scientists noticed several decades ago that electrodes placed on certain places of the nerves between the eyes and the brain would fire when different image components were seen.

For instance, one nerve would fire when a horizontal line was seen, other ones for vertical, diagonal, curved, etc. What they are doing here is detecting all these at once and putting them together in a very simplistic way.

So we're not any closer to System Shock styled mental powers? Poo.

This is a quantum leap in neuroscience.

Yes. But only for very small quanta.

Well, I was impressed. Though markedly more so here than on other sites where people are discussing it.

I am the Nate of other Internet forums.

Saw the headline on LL the other day. didn't believe it--thought it was just more of the aforementioned prepared cards.

THIS IS REALLY COOL

Really? As an LL reader, I’m surprised I didn’t notice it. Which entry is it?

What is this LL of which you speak?

Google sucks with some web searches. I'll assume it isn't Lincoln Laboratories.

My LL is Language Log. Any other LL is inferior.

Err, except Lorne.

If I’m drunk, does this machine read my thoughts blurrily too?
Posted 12-15-2008 at 09:40 AM by Wil

Nate's Avatar
I think drunkenness causes vision to be unfocused, which would mean that the input to the machine would be unfocused also. But then, some extra blurriness may happen in your brain, which would not affect the machine.

And now what are the effects of being hungover, missing lectures, and ignoring calls from the people you’re meant to be in the library with to put together a presentation for Thursday on this marvelous technology?

If we ever make a Dream Recorder, I am buying 1 for everybody I know. I fucking want one to exist so bad.

Lets just hope we dont need chips in our heads for it to work. Someone might recreate Scanners all over again.
