How Does It Work?

TMS Therapy


Through a treatment coil, the TMS Therapy system generates highly concentrated magnetic fields which turn on and off very rapidly. These magnetic fields are similar to those produced by a magnetic resonance imaging (MRI) machine.

The treatment coil is applied to the head above the left prefrontal cortex. This part of the brain is thought to be involved with mood regulation, and therefore is the best location to focus the magnetic fields. These magnetic fields do not directly affect the whole brain; they only reach about 2-3 centimeters into the brain directly beneath the treatment coil. As these magnetic fields move into the brain, they produce very small electrical currents. These electrical currents activate nerve cells within the brain which are involved in the regulation of mood.
