Today I was linked to a video by Snarky Bytes. It is a video documenting someone watching a video while in an MRI. The left side is the video as it was played, and the right is the reconstruction done based on the brain activity recorded by the MRI:
The left clip is a segment of the movie that the subject viewed while in the magnet. The right clip shows the reconstruction of this movie from brain activity measured using fMRI. The reconstruction was obtained using only each subject's brain activity and a library of 18 million seconds of random YouTube video. (In brief, the algorithm processes each of the 18 million clips through the brain model, and identifies the clips that would have produced brain activity as similar to the measured brain activity as possible. The clips used to fit the model, those used to test the model and those used to reconstruct the stimulus were entirely separate.) Brain activity was sampled every one second, and each one-second section of the viewed movie was reconstructed separately.
Um, _what_the_fuck_?
So creepy!
And I completely want an MRI machine now; this would make for some of the awesomest distorted video _ever_.
