Internal Voices Decoded by Scientists at UC Berkeley

March 9th, 2012 in News 1 comment


Researchers have developed a technique that reconstructs the words patients are thinking of that could help locked-in or comatose patients communicate.

A newly developed computer model reconstructs the sounds of words that patients think of. Over the past few years, scientists have been coming closer to being able to listen in to our thoughts. ┬áThis study achieved that goal by implanting electrodes directly into patients’ brains. In an earlier 2011 study, test subjects with electrodes in their brains were able to move a cursor around a screen just by thinking of different vowel sounds. Another study, conducted in September of that year by Jack Gallant at the University of California, Berkeley, was able to guess images being thought of through functional magnetic resonance imaging (fMRI).
