Brain Port: Tongue as a Superior Sense Processor.

To develop a super-solider of the future, researchers at the Florida Institute for Human and Machine Cognition are looking at tongues.

Yes, tongues:

By routing signals from helmet-mounted cameras, sonar and other equipment through the tongue to the brain, they hope to give elite soldiers superhuman senses similar to owls, snakes and fish. …

The device, known as "Brain Port," was pioneered more than 30 years ago by Dr. Paul Bach-y-Rita, a University of Wisconsin neuroscientist. Bach-y-Rita began routing images from a camera through electrodes taped to people’s backs and later discovered the tongue was a superior transmitter.
