Brain-Computer Interface Works With Speech Centers

Scottingham writes "Science Daily reports on new research that uses electrodes placed in the speech centers of the brain to move a cursor around the screen. Participants were instructed to utter different vowel sounds while their neural activity was parsed and analyzed. Once analyzed and connected to a cursor-control program, participants quickly learned to use the different vowel sounds to move a cursor around a screen. The system can distinguish between actual speech and the cursor controlling thought sounds."
