Spooky mind-reading implant placed deep inside your brain can decode your internal monologue with 80% accuracy

Scientists are one step closer to reading people's minds after developing new technology that can decode internal speech with nearly 80 per cent accuracy. Some people are unable to speak due to disease or injury, but devices called brain-machine interfaces (BMIs) can help patients communicate again. Also known as'speech decoders', BMIs can capture brain activity during inner speech – words thought within the mind without making any movement or sound – and translate it into language. Until now, it has been difficult to achieve highly accurate results. Researchers from the California Institute of Technology implanted tiny devices in specific areas of the brains of two participants.
