From France 24:
It’s a power associated with fictional superheroes, not the stuff of real life. But the capacity to read minds via direct neural interfaces, called brain-computer interfaces (BCIs), has advanced by leaps and bounds in recent years. A recent Stanford University study has made it possible to directly decode inner speech, or what a person thinks they are saying, without gestures or sound.
Researchers were previously able to give a voice to people unable to speak by capturing signals in the motor cortex of the brain as they attempted to move their mouths, tongues, lips and vocal cords. But the new Stanford University study has managed to bypass physical speech. But decoding our inner voice is not without risks. During trials, the implant sometimes picked up unexpected signals, requiring the implementation of a mental password to protect certain thoughts.
