Who would have thought, but the tongue has proved to be a superior transmitter to some exterior appendages. Known as the Brain Port, the device can link cameras, sensors, sonar and other equipment through the tongue. Pioneered more than 30 years ago by Paul Bach-y-Rita, a University of Wisconsin neuroscientist, the Brain Port has proved positive in testing with blind people who were able to see doors and catch balls. Other tests included the use of compasses by underwater divers. Paul and his team plan to present their findings to the military which could put the product on the fast track for further development and use in the field of combat.
