Reconstruction from brain activity

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 deceased's brain activity. The reconstruction is a fictional illustration allegedly 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 a model of each individual brain, and identifies the clips that would likely 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.

This is fake, its just the original video about reconstructing brain activity and this ass adding the "deceased" fake crap. Vote down, this is a fake video trying to piggyback off views.

@TheA1ternative This is a miniature scifi movie. Not a plot to piggyback views. What would anyone benefit from such views anyway?

@ldezem It's not a movie, they messed up the original and did something stupid to it. Reconstruction of brain activity is real. Look up "reconstruction of brain activity Scientific American" and you'll see its real.
