Zašto mi nitko nije rekao da je budućnost već došla? Nije je da precizno i izgleda ovisno čisto o korisnikovoj percepciji, ali potencijal je tu.

Indeed, it's mindblowing. I'm simultaneously excited and terrified. This is how it works:
They used three different subjects for the experiments—incidentally, they were part of the research team because it requires being inside a functional Magnetic Resonance Imaging system for hours at a time. The subjects were exposed to two different groups of Hollywood movie trailers as the fMRI system recorded the brain's blood flow through their brains' visual cortex.
The readings were fed into a computer program in which they were divided into three-dimensional pixels units called voxels (volumetric pixels). This process effectively decodes the brain signals generated by moving pictures, connecting the shape and motion information from the movies to specific brain actions. As the sessions progressed, the computer learned more and more about how the visual activity presented on the screen corresponded to the brain activity.
