Scientists at the University of California were able to pick up several words that subjects thought using a new mind-reading device.
It might seem the stuff of science fiction, but a mind-reading device is being developed by scientists which can evesdrop on your inner-voice. Reseachers at the University of California, Berkeley, have developed a machine and computer programme which converts brain activity into sounds and words. Speech activates specific neurons as the brain works interpret the sounds as words. Each word activates a slightly different set of neurons.
Now scientists have started to develop an algorithm that can pick up the activity and translate it back into words in the hope it might help people who are unable to speak.
