The future is here. Scientists can now read your mind. By using a computer to decipher brain activity, a computer can reconstruct those signals into actual words. This is a breakthrough, especially for people who are unable to speak and this tech here could help them generate a voice just by thinking in sentences.

"Potentially, the technique could be used to develop an implantable prosthetic device to aid speaking, and for some patients that would be wonderful," Robert Knight, a senior member of the team and director of the Helen Wills Neuroscience Institute at the University of California, Berkeley, told the Guardian. "Perhaps in 10 years it will be as common as grandmother getting a new hip."

The experiment involved 15 patients having the top of their skull removed and having a net of electrodes laid across the surface of their brain while they were having surgery.

The patients were then played a series of words for five to ten minutes while having their brain activity recorded. The research is published in PLoS Biology.
