In a recent study, researchers tested a device called a transcranial magnetic stimulator, or TMS for short, on a small group of 43 migraine sufferers.
The TMS generates a strong, one millisecond magnetic pulse that interrupts the symptoms leading up to a migraine, called the "aura" phase. Many migraine sufferers report zigzagging lines or bright flashes of light in their vision during this phase, as well as spreading blind spots and tingling sensations in their arms and legs.
EMP those damned migraines before they start.
