A recent experiment has been in the news these days. As the BBC writes:
Scientists have unveiled a new technique for decoding human brainwaves and then converting them into speech. The technique may one day make it possible to communicate with patients who are unable to talk.
This BBC video I’ve embedded provides the best explanation, and examples, that I’ve seen or heard:
I’ll probably use this with my IB Theory of Knowledge class when we study language.
This experiment relates to another one I have described in a previous post:
In an experiment, researchers were able to take the brain waves of people seeing what’s on the left and reconstruct the images on the right — only from brain waves. You can read about the potential implications of this process, ranging from identifying what patients in a coma are experiencing to seeing our own dreams, at Scientific American:
