Communication by Brain Waves Alone
Some victims of severe traumatic brain injury are unable to speak at all or speak unintelligibly. What if it were possible for them to wear a set of EEG headphones that recorded their internal thoughts in the form of EEG waves and transmitted their EEG waves via computer to another person? What if the other computer accurately decoded their EEG waves into words that the message recipient could understand and reply to? Based on collaborative research by two labs and two universities including Harvard Medical School this has just been done. This research was published in the online science journal Plos One in August 2014.
