- Pulsed magnetic fields induce small electric currents in the left prefrontal cortex of the brain
- Local brain cells or neurons underneath the magnet depolarize, causing an action potential and the release of neurotransmitters
- Distant areas of the brain are activated and existing as well as new neural networks and pathways are strengthened and created
- Increases in blood flow and glucose metabolism rise in the stimulated areas is also thought to result in improved mood
- Repeated stimulation of the left prefrontal cortex is shown to produce antidepressant effects in patients suffering from major depression.
- TMS targets brain regions involved in mood regulation without the systemic side effects and problems that are seen in antidepressant medication.
