Using Computers to Read Minds.

A new study has shown that technology is making telepathy possible: brain activity is being correctly translated into text.

Featured in Frontiers in Neuroscience, a study conducted by the National Center for Adaptive Neurotechnologies and the State University of New York at Albany had seven patients with electrode sheets placed on their brains read aloud from famous texts – the Gettysburg Address, JFK’s inaugural speech, and Humpty Dumpty.

From this data, a computer learned to connect certain sounds with their associated brain cells, and proved able to “read” brain cells with a 75% accuracy rate. From there, an "autocorrect" system is used through which the most likely combinations of sounds were chosen to translate words at an even higher rate of accuracy.

At this point, data has to be read directly from the brain rather than through the scalp, which is why this experiment was conducted on patients who were already undergoing epilepsy related surgery.

While clearly not applicable to the average consumer, this work does show promise in application for people with ALS, or related neurological diseases.
