Brain Images

I read an article, although it was dated back to 2008, about researchers in Japan that have created technology to take images from the brain and reconstruct them outside of the brain, like on a computer. These researchers say that they can even take it as far as to be able to view peoples' dreams in the upcoming future. The technology behind being able to reconstruct the images deals with an fMRI scan, allowing the scan to see the blood flow in the brain at real time. As the fMRI scanner was scanning the blood flow of the brain, images were shown to the subjects of the testing, allowing the computer to put together the connection between how the blood flows in the brain based upon the certain images being shown. I do believe that this technology is a forefront in modern medical and psychological technology, but it slightly scares me. It scares me that in the future, advertisers or companies could be able to not only take images from our brain, but implant images into our brain in order to make us think a certain idea.
