I ricercatori dell’università di Berkeley hanno creato un sistema per decriptare le onde cerebrali e permettere di vedere ciò che stiamo pensando.

Il sistema testato si chiama FMRI (functional magnetic resonance imaging), in pratica gli scienziati hanno creato un archivio con 18 milioni di secondi di video di YouTube. Quando il soggetto si fa analizzare e viene sottoposto a delle immagini il suo cervello produce delle onde. Le onde vengono confrontate con quelle registrate nella visione dei video di Youtube.

Ecco un estratto della ricerca

The brain activity recorded while subjects viewed the first set of clips was fed into a computer program that learned, second by second, to associate visual patterns in the movie with the corresponding brain activity. Brain activity evoked by the second set of clips was used to test the movie reconstruction algorithm. This was done by feeding 18 million seconds of random YouTube videos into the computer program so that it could predict the brain activity that each film clip would most likely evoke in each subject. Finally, the 100 clips that the computer program decided were most similar to the clip that the subject had probably seen were merged to produce a blurry yet continuous reconstruction of the original movie.
