Neuroscientists reveal the brain malady responsible for tinnitus, chronic pain

Neuroscientists at Georgetown University Medical Center and Germany’s Technische Universität München say they’ve uncovered the brain malady responsible for tinnitus and for chronic pain — the uncomfortable, sometimes agonizing sensations that persist long after an initial injury. In the October issue of Trends in Cognitive Sciences, researchers say identifying the problem is the first step to developing effective therapies for these disorders, which afflict millions of people. None now exist. The scientists describe how the neural mechanisms that normally “gate” or control noise and pain signals can become dysfunctional, leading to a chronic perception of these sensations. They traced the flow of these signals through the brain and showed where “circuit breakers” should be working — but aren’t. In both disorders, the brain has been reorganized in response to an…
