From the brain side, those of us who remember the pallidotomy and thalamotomy days, the "noninvasive" part is a marketing misnomer. It's invasive (it's a lesioning/ablation therapy); it just doesn't require a pallidotomy. But it's a shockingly effective tactic; there's a steady stream of patients rolling in the office with mild symptoms who are willingly requesting to have a hole burned in their head. (Also it's turning out not to be nearly as effective in treating symptoms as deep brain stimulation)
