Unbearable headaches and sensitivity to bright lights could be a thing of the past. The hand-held migraine zapper is a gadget which produces short but strong, low-frequency magnetic pulses that suppress the spread of a migraine, though exactly how, isn't well understood at this time. The device is a spin-off of neuroscientific studies attempting to identify functions of different parts of the brain. Using the technique of transcranial magnetic stimulation or TMS, researchers found that they could map the different parts of the brain that deal with (or are somehow associated with) language, memory, and vision etc. They did this by either stimulating them or suppressing them, applying different TMS signals to different parts of the brain. The device has yet to achieve FDA approval.
