Berkeley scientists reconstructed clips from brain scans of those who just watched it  (Source:
Using fMRI and computational models, researchers were able to decipher and reconstruct movies from our minds

Researchers from the University of California-Berkeley have used functional Magnetic Resonance Imaging (fMRI) and computational models to watch clips of movies inside the minds of people who just viewed them.

Jack Gallant, study leader and a UC Berkeley neuroscientist, and Shinji Nishimoto, a post-doctoral researcher in Gallant's lab, were able to "read the mind" by deciphering and rebuilding the human visual experience.

In previous studies, Gallant was able to 
record activity in the visual cortex (which processes visual information in the brain) while participants viewed black-and-white photos, and then use a computational model to predict what the participant was looking at. 

Now, Gallant and his team have decoded brain signals created by viewing moving pictures
. They were able to do this by placing Nishimoto and two other research members in a MRI scanner while they viewed two sets of Hollywood movie trailers. While watching the first set of trailers, the fMRI measured blood flow through the visual cortex and this information was directed to a computer, which portrayed the brain as tiny three-dimensional cubes called "voxels," or volumetric pixels. For each voxel, there was a model that detailed how motion and shapes in the movie are translated into brain activity. The computer program learned to relate visual patterns in the trailers with corresponding brain activity. 

The second set of clips tested the computer's algorithm by giving it 18 million seconds of YouTube clips allowing it to eventually predict the brain activity that each clip would induce. 

Then, a reconstruction of the original trailer was produced by merging 
brain scans that were most similar to the YouTube clips. The end result came out a bit blurry, but represents a large step toward reconstructing images humans see and process.

The team hopes that this research can lead to technology that can decipher what is happening in the minds of those who cannot communicate verbally, such as 
stroke victims or coma patients. Eventually, this could lead to the creation of an interface that allows people (with paralysis, for instance) to use their minds to control machines.

Mind reading won't help; there is no answer.

If you're a husband, you already should know that you were not her first choice.

To be fair, neither was she. ;)

You read my mind, man! I was going to say the same thing. I want to get one of these things for my wife! Hopefully it'll be kind of discreet like a hidden webcam or something like that.

I'm Sorry

I just want to apologize in advance to everyone I know who has a hot sister.

LOL. Im Married and will have some explaining to do.

For me this is the most amazing technology of the decade. If one day they can make it available to everyone and perfect it.

I imagine my kids coming it saying they had a nightmare and being able to see what scared them. I also wonder what a psychopath might dream about or envision in their mind. The possibilities are endless.

Yay! All artists will be out of jobs! No more need to spend $300 million on the latest CG blockbuster. Just think it!

Seriously though, the human body is far more adept at input than output. Sight, smell, sound, touch, taste give us all this massive level of input, and our brains are massively complex machines which can create entire realities in the blink of an eye (dreams, imagination). But when it comes to outputting all this in our heads, it's like pulling teeth times 1 million! Spending decades trying to train your stupid hand how to put on paper what you see in your mind, learning speech, etc.) This kind of research may some day lead to a fairly high bandwidth output source for us all finally. Very interesting.

So what I took from the picture, is apparently the person in the MRI was mentally undressing Steve Martin. Fortunately they only took him from wearing a dress uniform and cap to wearing a t-shirt.

Also, the background being drawn almost looks like a bathroom, or a closet off to the right, it looks like clothes hanging.

So it looks like the movie pulled up a memory and that is what got drawn, not the memory of the movie clip, but something the movie clip triggered.

Try doing a search on youtube for "electronic harassment", "targeted individuals" and the like.

Also, if you care, sign a partition about how much you like this cool technology for the US Govt.

Watching a movie, and allowing others to see what you're watching? Sounds like a public performance to me. Bunch of pirating criminals, if you ask the MPAA.

In the future, people will post their dream on YouTube!

Ummm.... Let me guess!

"The 6th Day", anyone?

Reminds me of Arnold Schwarzenegger's "The 6th Day."

This isn't mind reading

This is not mind reading. This is a recreation of an image, through the brain, of what you are currently seeing with your eyes. And it involves hooking hundreds of wires to your brain. It does not recreate thoughts, emotions, or past events though it likely could render those types of images at some point in the future.
