Scientists have been working on a brain translation machine that would possibly allow thought-to-speech possible. Of course, this means that in the future, we can possibly keep the brain alive even if the human body is dead, sorta like science fiction.
By implanting an electrode into the brain of a person with locked-in syndrome, scientists have demonstrated how to wirelessly transmit neural signals to a speech synthesizer. The “thought-to-speech” process takes about 50 milliseconds – the same am
