Scientists from Japan and the United States have figured out how to read a person's mind by remotely measuring brain activity, extracting information of which the subject is not even aware. Science fiction? No. It's real.
So far it's
pretty rudimentary stuff in that the mind-reading machine can only identify
visual patterns a volunteer can see or has chosen to look at. But the
researchers are hopeful that the approach will eventually probe into a
person's awareness, focus of attention, memory, and movement intention,
report New Scientist and Scientific American.
Here's an eye-popping finding: When two sets of patterns were superimposed and the volunteers were told to focus on just one of them, the researchers were able to tell from the brain images which one they were looking at!
One exciting application: Doctors could use it to find out if comatose patients are actually conscious.
findings were published in the journal Nature Neuroscience.
