The soldier of the future will be a robot?or a man-machine, anyway. Maybe the rest of us will be too. The military is looking for ways to send signals directly to a soldier’s brain, without having to go through another human being. They’ve discovered a unexpected direct route to the brain: the human tongue.
Researchers at the Florida Institute for Human and Machine Cognition want to be able to send signals from cameras and sonar into soldiers? brains, so that they can gain hearing and sight of animals like owls and snakes. Our tongues are ultra-sensitive receptors, which anyone realizes who has ever had a filling or a cap put in. The tongue investigates the new addition to the mouth unceasingly, until it knows every nook and cranny.
