What Is TMS (Transcranial Magnetic Stimulation) ?

Transcranial Magnetic Stimulation is a procedure that uses magnetic fields to stimulate nerve cells in the brain. Transcranial magnetic stimulation is one of the newer types of brain-stimulation methods designed to treat different mental conditions  when standard treatment hasn't worked.

An electromagnetic coil is placed against your scalp near your forehead. The electromagnet creates painless electric currents that stimulate nerve cells in the region of your brain involved in mood regulation and Depression .

How Does It Work ?

During transcranial magnetic stimulation, the magnetic pulses create painless electrical currents in your brain. These currents stimulate nerve cells in the region of your brain involved in mood regulation.

  • specialist influences the electrical activity in the brain by means of a pulsed magnetic field. The magnetic field is generated by passing brief current pulses
  • This coil of wire is held close to the scalp so that the magnetic field can be focused onto specific areas of the cortex, or surface, of the brain
  • The magnetic field that is generated in rTMS can penetrate the scalp and skull safely and painlessly to induce a current in specific neurons (brain cells)
  • Because the magnetic stimulation is delivered at regular intervals, it is termed repetitive TMS, or rTMS

Stimulation parameters, such as the number of stimuli, the strength of the stimuli, the duration of the stimuli, and the length of the interval between stimuli can all be varied.

The ability to change parameters while directly targeting specific brain cells suggests that rTMS therapy has an extremely valuable therapeutic potential and treatment can be customized for each patient.
