On which new medicine (like XEN) or treatment would you place your bets @PortugalTheMan ? Personally, though I have some reservations, I do think that Dr. De Ridder's treatment has some merits. Ketamine might help us dissociate from tinnitus (=change self perception vs. default network) & the new HD-tPNS might be more effective in brain manipulation due to close mimicking the natural fire pattern of neurons
