【英语时差8,16】偏头痛-下

 By hitting the nerves with a mild electrical jolt¹, you can “distract” the signal-carriers–that is, the pain signals stop crossing the nerves for as long as the electrical charge is on. So how to do that? Levy² and others have inserted a little battery under patients’ collarbones, connected it to a wire that runs under the scalp, and stuck the end directly into the misfiring nerve. Odd as it may sound at first, it works. Patients report that when the device is turned on they are pain-free, sometimes for the first time in years. This kind of nerve stimulation³ is still in its early days, but the results so far look very promising⁴. For chronic⁵ headache sufferers, a little wire can make for blessed peace of mind…not pain of head.
