Transcranial Magnetic Stimulation (TMS) therapy is an advanced, non-invasive treatment option for individuals dealing with depression, anxiety, and other mental health conditions. While many have heard about the effectiveness of TMS, fewer understand how it works—specifically, how it targets the prefrontal cortex, a key area of the brain responsible for mood regulation, decision-making, and executive function.
In this blog, we’ll explore why the prefrontal cortex is so important in mental health and how TMS therapy is designed to stimulate this region for therapeutic benefit.
Why the Prefrontal Cortex Matters
The prefrontal cortex is located at the front of the brain, just behind the forehead. This region plays a vital role in:
- Regulating emotions
- Managing attention and focus
- Making decisions and solving problems
- Forming and evaluating goals
- Processing complex thoughts and social behavior
In people with major depressive disorder (MDD), the prefrontal cortex—especially the left dorsolateral prefrontal cortex (DLPFC)—is often underactive. This lack of activity disrupts communication between neural networks, leading to symptoms such as persistent sadness, lack of motivation, poor concentration, and feelings of hopelessness.
How TMS Therapy Stimulates the Prefrontal Cortex
TMS therapy uses a magnetic coil placed gently on the scalp near the forehead. This coil delivers targeted magnetic pulses to the left DLPFC, stimulating the nerve cells beneath the surface. These pulses help:
- Increase neural activity in areas of the brain that are underactive
- Enhance neurotransmitter release, including serotonin and dopamine
- Restore balanced brain function, improving emotional and cognitive regulation
Because the stimulation is focused and repetitive (repetitive TMS or rTMS), it can lead to lasting improvements in brain connectivity and function.
The TMS Treatment Process
- Mapping the Brain
During the first session, a trained provider performs a “motor threshold” test to locate the ideal spot for stimulation and determine the correct dose. This ensures that the magnetic pulses are precisely targeted to the patient’s prefrontal cortex. - Regular Sessions
Treatment typically involves 5 sessions per week over 4–6 weeks. Each session lasts 20–40 minutes. While receiving TMS, patients sit comfortably and remain awake. Most feel a tapping sensation on their forehead but no significant discomfort. - Gradual Improvements
As the prefrontal cortex is repeatedly stimulated, patients often experience improvements in mood, energy, and mental clarity. These changes build over time, with many people seeing noticeable progress by week three or four.
Safety and Effectiveness
TMS therapy is FDA-approved for treatment-resistant depression and is considered safe with minimal side effects. Since it directly targets the brain area involved in mood control, it can be especially effective for those who have not responded to medication or psychotherapy.
Studies have shown that stimulating the prefrontal cortex not only improves symptoms of depression but can also positively affect anxiety and PTSD symptoms, thanks to the interconnected nature of brain regions involved in emotional processing.
