TMS devices work by generating highly concentrated electromagnetic pulses which turn on and off very rapidly. These pulses are targeted at areas of the brain involved in mood regulation and shown to be inactive in patients suffering from depression.
As these magnetic fields move into the brain, they produce very small electrical currents. These electrical currents are thought to activate brain cells in these inactive regions and release neurotransmitters like serotonin, norepinephrine, and dopamine – all of which work to naturally help lesson the symptoms of depression.
The exact mechanics of TMS Therapy are still of an unknown origin, but the science behind TMS is constantly being explored and understood. Today, researchers can only observe the effects that electromagnetic stimulation from TMS has on the brain. However this is changing as more study goes into TMS technology.
