It is possible to read someone?s mind by remotely measuring their brain activity, researchers have shown. The technique can even extract information from subjects that they are not aware of themselves.
So far, it has only been used to identify visual patterns a subject can see or has chosen to focus on. But the researchers speculate the approach might be extended to probe a person?s awareness, focus of attention, memory and movement intention. In the meantime, it could help doctors work out if patients apparently in a coma are actually conscious.
