Dear friends and colleagues,
We want to inform you about the latest news in tinnitus research.In order to download the 15th TRI Newsletter please use the following link:
Tinnitus Research has evolved remarkably in the last years. Year after year there
are more publications dealing with tinnitus, and - probably even more important - the
methodological and scientific quality of research improved enormously. It is impressive
how many tinnitus studies appeared in the last three months in most prestigious journals
such as Journal of Neuroscience, Neuron or Nature. Thus tinnitus as a research topic
reached the best labs and the brightest minds, a development which is also reflected
by a tinnitus symposium at the last year's Meeting of the Society for Neuroscience. This
means that tinnitus has finally reached the stage where it has become a scientifically
acceptable and intellectually interesting matter to study.

means that tinnitus has finally reached the stage where it has become a scientifically
acceptable and intellectually interesting matter to study.
This development is of fundamental importance for all patients suffering from tinnitus,
since the better the underlying mechanisms are understood, the higher the chances
for more effective treatments in the near future. In addition, from a mere statistical
point of view this change is also important. Many more young bright researchers will
start investigating this enigmatic symptom, increasing the chances that someone will
be bright or lucky enough to make a real breakthrough. Once a critical mass of highly
motivated young people start investigating the problem, a final solution is more likely.
Although initially probably not every single person suffering from tinnitus will find a cure,
an increasing number of patients will find relief over time.

It is one of the main priorities of TRI to communicate these latest research results.
Thus we decided to add an additional section to the newsletter, where we inform about
recent research highlights. You will find an overview of this new section below.

The amount of new high quality research is also the motivation for the motto of this
year's TRI Meeting: "The Neuroscience of Tinnitus". We invite all of you to join us
in Buffalo in August to share the most recent research results and to discuss future
research directions and implications for clinical management. As usual you can find more
detailed information regarding the meeting on the TRI website www.tinnitusresearch.org

Let us embrace this wonderful scientific momentum and work even harder and together,
basic scientists and clinicians alike, to find a solution.
