Tinnitus—a constant ringing or buzzing in the ears that affects about 15% of people—is difficult to understand and even harder to treat. Now, scientists have shown shocking the tongue—combined with a carefully designed sound program—can reduce symptoms of the disorder, not just while patients are being treated, but up to 1 year later.

When he inserted a pencil-size rod covered in electrodes directly into the brains of five patients, some of those electrodes landed slightly outside the target zone—a common problem with deep brain stimulation, Lim says. Later, when he started up the device to map out its effects on the brain, a patient who had been bothered by ringing ears for many years, said, “Oh, my tinnitus! I can’t hear my tinnitus,” Lim recalls.
This is what I want: a DBS electrode to knock out the area of my brain/auditory cortex producing the tinnitus.
Why not making the best of both worlds and saying your tinnitus goodbye whilst learning your ropes on electronics, by performing the wacky tongue experiment* shown on Charles Platt's iconic book? (fig. 1-16) :))

* Which involves licking up a 9-volt battery, but one can always "upgrade" to a higher-voltage one - just sayin'!
