About 10 percent of the population  suffer from tinnitus. It is a constant, often high-pitched ringing or buzzing in the ears that can be annoying and even maddening, and has no cure. However Neuroscientists at the University of California, Berkeley are studying 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.
I think their study of this is very beneficial to us. Those suffering from tinnitus can be cured so they do not have to bear with the ringing and buzzing inside their ear anymore. This study by the neuroscientists will definetly benefit us.
