Using brain scans, you can spy on what you dream

The scientists were able to develop a technique of decoding brain impulses, allows us to understand the category to which your dream, up to 60%.

The fact that in our dreams often repeated the same visual images, such as "tree" or "person." Researchers have identified about 20 major categories developed separately for each participant. Note that items such as, for example, the "ice pick", "key" and "piston" belong to the same category - "guns».

Three volunteers were asked to look at pictures from the Internet, corresponding to these categories, and at this point their brain activity was monitored. Then the obtained data were entered into a specially designed computer program then scans continued even during sleep. Researchers led by neurologist Yuki Kamitani at this point monitored the brain activity of subjects. As soon as possible to determine what the volunteers saw in a dream, they were awakened and asked to describe their dreams.

So far, the system is far from perfect and can only guess the visualization of a wide range of categories. Decoding the same items dream at the moment is not possible.
