- 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.
What About Side Effects?
Compare the side effects of commonly prescribed antidepressants with those of TMS.
