Tinnitus discovery could lead to new ways to stop the ringing: Retraining the brain could reanimate areas that have lost input from the ear

People with tinnitus -- a constant ringing or buzzing in the ears -- can take heart from a new study by neuroscientists that points to several new strategies for alleviating the problem. In experiments on rats, researchers have shown that tinnitus results from decreased inhibition in the auditory cortex. Thus, training that boosts inhibition or drugs that increase the levels of inhibitory neurotransmitter may alleviate the symptoms.
