Scientists decode ‘internal voices’
Posted February 25, 2012on:
Researchers have demonstrated a striking method to reconstruct words, based on the brain waves of patients thinking of those words.
The technique reported in PLoS Biology relies on gathering electrical signals directly from patients’ brains.
Based on signals from listening patients, a computer model was used to reconstruct the sounds of words that patients were thinking of.
The method may in future help comatose and locked-in patients communicate.
