Ampa One System - The Ampa One System is a computerized, electromechanical medical device that produces and deliversnon-invasive, magnetic fields to induce electrical currents in brain tissues to target specific regions of thecerebral cortex. The system contains two different coils for targeting different regions of the brain. The LCoil is designed to target the left dorsolateral prefrontal cortex (DLPFC). The M Coil is designed to targetthe bilateral prefrontal cortex (DMPFC). Both coils are used within the Ampa One System to treat MajorDepressive Disorder (MDD) in adult patients who have failed to receive satisfactory improvement fromprior antidepressant medication in the current episode.Transcranial magnetic stimulation (TMS) is a non-invasive technique for stimulating brain and neuraltissue. The principle of magnetic stimulation is implicit in Faraday's law. The pulses of current aregenerated with a circuit containing a capacitor connected to the stimulating coil. With the capacitorcharged to a certain level, the conducting state will cause the discharging of the capacitor through the coil.A magnetic field is generated proportional to this current. The rapid change in the magnetic field inducesa current in conducting materials e.g. the body tissue. If the current induced in the human body is ofsufficient amplitude and duration, it will excite neurons.
