Transcranial magnetic stimulation (TMS) is a noninvasive procedure, and it uses magnetic fields to target specific brain regions. Doctors may use it when other treatments have not worked, and it does not require surgery or anesthesia. If you are learning about your options, understanding how TMS works helps you be prepared. Here is more information about the TMS process and how it works:
Delivering Magnetic Pulses
A trained technician places a magnetic coil against your scalp during each session. The coil generates brief magnetic pulses, and these pulses pass painlessly through your skull. Since the field targets a precise area, TMS treatment typically focuses on regions linked to mood regulation.
The pulses repeat at set intervals throughout the appointment. When the coil activates, you may feel a light tapping sensation on your head. You stay awake and alert the entire time, so daily activities resume right after.
Stimulating Nerve Cells
The magnetic pulses reach neurons, which are the nerve cells beneath the coil. These neurons respond to the magnetic field, and the field prompts them to fire. Firing describes the moment a neuron sends an electrical signal to nearby cells.
Different frequencies affect nerve cells, and they work in various ways. Some protocols use rapid pulses, while slower pulses suit other treatment plans. Your provider selects a frequency based on the region being treated:
- High-frequency pulses to encourage activity
- Low-frequency pulses to reduce activity
Since each brain differs, technicians measure your response before treatment begins. This measurement, called the motor threshold, guides the pulse strength. Your comfort and safety shape how the settings are adjusted during each session.
Increasing Electrical Activity
Repeated stimulation raises the electrical activity in the targeted region. Neurons that fire together strengthen their connections, and this pattern builds over multiple sessions. Researchers describe this gradual change as neuroplasticity.
A single session produces short-term effects on brain activity. When sessions repeat across several weeks, the changes accumulate. Your treatment schedule reflects this need for consistency.
This process demonstrates how the brain can adapt to repeated stimuli in a structured manner. Regular and consistent sessions are essential to achieving lasting effects. While short-term effects may be noticeable after a single session, the cumulative impact over time is what leads to meaningful, long-term changes.
Restoring Communication Pathways
Brain regions communicate through networks of connected cells. TMS aims to strengthen weak signals between these regions, and the process targets pathways tied to mood. When communication improves, related networks may function more smoothly.
Your provider monitors your progress throughout the treatment course. Adjustments happen if the response differs from what was expected, so the plan stays matched to your needs. These check-ins keep the process on track. Staying informed may help simplify the treatment process.
Schedule TMS Therapy Sessions
TMS follows a clear sequence, and each session builds on the last. Your provider tailors the schedule to your specific situation.
