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.
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. In both disorders, the brain has been reorganized in response to an injury in its sensory apparatus, says Josef Rauschecker, PhD, DSc, director of the Laboratory for Integrative Neuroscience and Cognition at GUMC. Areas of the brain responsible for these errant sensations are the nucleus accumbens, the reward and learning center, and several areas that serve "executive" or administrative roles --the ventromedial prefrontal cortex (VNPFC) and the anterior cingulate cortex. All of these areas are also important for evaluating and modulating emotional experiences, Rauschecker says. Ironically, the brain plasticity that produces some of these changes provides hope that this gatekeeping role can be restored, Rauschecker says.
Rauschecker, an expert in tinnitus, collaborated with Ploner, who studies chronic pain, during his senior fellowship at the Institute of Advanced Study at TUM.
The National Institutes of Health (RC1-DC010720), the American Tinnitus Association, the Skirball Foundation, the Tinnitus Research Initiative and the Tinnitus Research Consortium have supported tinnitus research in the Rauschecker lab. Georgetown University Medical Center (GUMC) is an internationally recognized academic medical center with a three-part mission of research, teaching and patient care (through MedStar Health).

Morrison Dental Group has Dentists in Newport News, Williamsburg, Norge & Chincoteague, VA. They traced the flow of these signals through the brain and showed where "circuit breakers" should be working -- but aren't. Tinnitus can occur after the ears are damaged by loud noise, but even after the brain reorganizes itself, it continues to "hear" a constant hum or drum.
Because these systems rely on transmission of dopamine and serotonin between neurons, drugs that modulate dopamine may help restore sensory gating, he says. Our Williamsburg VA Dentists are highly rated among patients and always provide the highest quality dental care.

Chronic pain can occur from an injury that often is healed on the outside but persists inside the brain. Our treatments aid in relieving the cause of many headaches and headache-pain symptoms, and provides long-lasting, needle-free, and drug-free pain relief. Using a combination of techniques derived from sports medicine therapies, our Migraine Therapy System targets the improper muscle forces in the head, neck, and jaw area that cause painful conditions. If you have been experiencing chronic migraines, headaches, neck pain, TMJ, ringing in the ears, dizziness, or a combination of these symptoms without finding relief, we may be able to help. If you are looking for a dentist in Newport News, Williamsburg, VA, Norge or Chincoteague, give us a call today.
Additionally, painful symptoms could result from an accident, head trauma, bad posture, or other underlying conditions. By treating the cause of the pain and not just the symptoms, Morrison Migraine Center provides long-lasting pain relief.
