We use an FDA approved, non-invasive brain stimulation technology called transcranial magnetic stimulation (TMS) which utilizes targeted magnetic pulses to modulate neural activity. This is a similar type of magnet as in an MRI machine. TMS has been safely used for over 15 years since its FDA approval in 2008.
Your brain's circuitry is based on electromagnetic signals. Specific magnetic pulse patterns, when delivered to a specific circuit, can cause more or less firing. TMS works in this way to up or down regulate circuits involved in the mental experiences you want to change - like improving mood, energy, or reducing rumination.
Using specific magnetic pulse patterns, TMS encourages your circuitry back to their optimal, healthy firing pattern. Much like how consistent exercise strengthens particular muscle groups, periodic use of stimulation optimizes your brain activity towards its natural, healthier state.
