I try to choose my battles. This isn't one of mine.
I've already done a reasonable amount of reading, they don't really have an agreen on mechanism for tinnitus. And I've spent time learning a bit of biology.
Actually tried that. "Descending Control", particularly in the auditory system isn't particularly well studied yet.
Actually, nerves might have both more and fewer free variables than coax. You can yank out the coax and solder in a different one. That is more of a problem if you tried to suggest doing that with the nervous system. But the nerve conduction speed is dependent on a variety of factors that might be open to modification, finding a way to adjust the thickness of the insulating meilin of the nerves is just one possibility. Perhaps there are other even more elegant ways to do this that would satisfy questions about whether the change was simultaneously changing other things in the system.
