Very good finding!
Look here:
Specific activation of operculum 3 (OP3) brain region during provoked tinnitus-related phantom auditory perceptions in humans
I always suspected my tinnitus as of somatosensory origin and the link that I just posted has a confirmation of it. My tinnitus came from a very clogged middle ear and local inflammation due to an external ear canal fungus. The fungus was cleared in days with ear drops, but they gave nothing for inflammation. My ear unclogged itself after 2 months, and bad tinnitus followed, in both ears. Which will explain again the somatosensory connection that gave tinnitus at the same time in my previously good ear. And again that I have 0 ear problems (sensitivity, distortion, pain...), but awful reactivity which made my tinnitus much worse in time.
I will write an email to the contact person in the study, Stéphan CHABARDES. Actually I just called him earlier and he was in a surgery. Got to be a way to break this awful tinnitus cycle.
