Cefaly's electric impulses target migraine relief at nerve cells. From a physiological perspective, only two types of cell respond to electrical stimulus: muscle cells and nerve cells.
The nerve in the head known to be associated with headaches is the trigeminal nerve. The main branch divides into two at the level of the orbit. The Cefaly electrode covers this bifurcation and therefore acts on this main part of the trigeminal nerve. Through this electrode, Cefaly transmits impulses that are specific and perfectly adapted to the trigeminal nerve.
Cefaly works on the endorphin-producing fibres of the trigeminal nerve. Endorphins are the neuro-hormones that provide a feeling of wellbeing. With a higher level of endorphins, the trigger threshold for a headache or migraine is altered, and therefore there are therefore fewer such attacks.
Another Cefaly program stimulates the touch sensitivity fibres of the trigeminal nerve. Affected at higher frequency, this offers further headache relief by partially blocking the entry of pain into the nervous system. This mechanism is called the gateway control system. In other words, the influxes of touch sensitivity are increased to the point that they do not leave any space for the influx of pain stimulus.
