Cefaly works by introducing safe, and painless electric impulses to act on the very nerves that transmit migraine pain, a bifurcation of nerves known as the trigeminal nerve. Often referred to as "the great sensory nerve of the head and neck", the trigeminal nerve is an Endorphin-producing mechanism that carries information about touch, temperature, perception and pain from the face and scalp to t
he brainstem. The patented Cefaly design covers this bifurcation and therefore acts on the main part of the trigeminal nerve. Through an electrode covering the middle of the forehead, Cefaly sustains a constant link between migraine pain specific nerves and the electric impulses it generates. Cefaly transmits extremely specific and perfectly adapted electrical impulses to safely stimulate the trigeminal nerve. Cefaly generates very precise electrical impulses to stimulate the nerve fibers selectively. As the impulses are produced very slowly, they are virtually imperceptible. Cefaly’s advanced technology enables an electronic feedback mechanism to adjust the electrical impulses to the specific requirements of the individual user for personalized efficacy and comfort. Cefaly specifically stimulates the endorphin-producing, and the touch sensitive nerve fibers of the trigeminal nerve. Cefaly purposely increases the production of endorphins and the influx of touch sensitivity - a mechanism called the Gateway Control System – both are increased to the point that they do not leave any space for the influx of pain stimulus. With a higher level of endorphins, the trigger threshold of headaches or migraine pain is altered by partially blocking the entry of migraine pain into the nervous system.
