Computer Program Reconstructs Heard Words From Brain Scans 147

sciencehabit writes "In a new study, neuroscientists connected a network of electrodes to the hearing centers of 15 patients' brains and recorded the brain activity while they listened to words like 'jazz' or 'Waldo.' They saw that each word generated its own unique pattern in the brain. So they developed two different computer programs that could reconstruct the words a patient heard just by analyzing his or her brain activity. Reconstructions from the better of the two programs were good enough that the researchers could accurately decipher the mystery word 80% to 90% percent of the time. Because there's evidence that the words we hear and the words we recall or imagine trigger similar brain processes, the study suggests scientists may one day be able to tune in to the words you're thinking."
