Discovered - the part of your brain that makes your ears ring.

Are you one of the millions of people in the world that hear a constant ringing in your ears? Then you'll be happy to know that researchers have figured out where in the brain that ringing- called Tinnitus - originates.

Using PET imaging, a technique for mapping activity in the brain, researchers have discovered that the phantom ringing isn't based in the cochlea or other ear parts at all. It actually originates deep inside the central auditory system.
