Moderators, feel free to move this thread if you find it off topic. I posted it because this describes what Dirk De Ridder tries to do with tinnitus: identifying cortical zones overactive and taming them with electrodes.
A man had neuropathic pain due to tumor removal on his face. He was successfully treated by an electrode sewed on his dura mater. Later he was operated on again and got additional pain. Since reprogramming the electrode didn't work the physicians observed his brain activity trough fMRI and PET-scan while provoking pain by soft stimulation (allodynia). They found two new oveactive sites on his cortex. They sewed two new electrodes and the man is again pain free.
