A group of scientists from Berkley University in California have developed a brain signal decoder that is able to reconstruct images of the perceptions of a person through a computer model.
So far, this technique, which combines magnetic resonance imaging (MRI) and images on the computer, can only reconstruct images of the videos that volunteers have seen before.
Shinji Nishimoto is the creator of the scanner that measures blood flow in the visual cortex, the zone were the brain treats the images it perceives.
Experts of the medical community believe that this breakthrough, published in the American magazine Current Biology, could be helping people that are in a prolonged coma. (AV)
