How fMRI-guided TMS therapy works
If you’ve been living with symptoms that won’t let up, such as low mood, constant worry, brain fog, attention problems, or changes after a concussion or other injury, you may be looking for something more precise than trial-and-error care.
At Neurotherapeutix on Manhattan’s Upper East Side, we take a different approach: we treat the brain you actually have, not the “average” brain in a protocol.
Neurotherapeutix is the only clinic in the United States offering fMRI-guided TMS therapy, combining computational brain mapping with carefully targeted neuromodulation to support healthier communication within the brain’s networks.
If you’d like to start with logistics, you can request an appointment or contact us anytime.
What is fMRI-guided TMS therapy?
fMRI-guided TMS therapy is a non-invasive treatment that uses:
- Computational brain mapping to measure brain activity and connectivity, and
- TMS stimulation to gently influence specific brain targets involved in symptoms.
Instead of guessing where to stimulate based on scalp measurements or “standard coordinates,” Neurotherapeutix uses computational brain mapping to identify the brain networks most connected to your symptoms, and then targets those networks with precision.
This personalization matters because research consistently shows that where stimulation is delivered can influence outcomes.
For example, connectivity-based targeting has been associated with antidepressant response, including findings that connectivity between a common TMS target (left dorsolateral prefrontal cortex) and the subgenual cingulate is linked to clinical response in major depression.
What an fMRI-guided TMS session feels like (and what you can do afterward)
During a session, a small magnetic coil rests against your scalp. You’ll feel a tapping sensation and hear clicking sounds. Most people describe it as unusual but manageable.
- Sessions typically take about 20–30 minutes.
- No anesthesia is needed.
- You can usually return to normal daily activities right away (work, school, errands).
The step-by-step fMRI-guided TMS therapy process at Neurotherapeutix
Below, you’ll see how we move from imaging to targeted stimulation — using data to guide every decision.
Step 1: fMRI scan to measure your brain’s networks
Your care begins with a functional MRI scan. This produces a detailed picture of how different brain regions “talk” to each other.
Because this scan is used to guide treatment (not just document anatomy), the goal is to identify connectivity patterns that may be linked to symptoms, like networks related to mood regulation, attention control, or cognitive speed.
Step 2: clinical and neuroscience analysis of connectivity patterns
Next, our team reviews the scan results to identify patterns such as:
- underactive or overactive regions
- poor synchronization between nodes in a network
- connectivity signatures associated with symptom clusters
This step turns “images” into a usable clinical map.
Step 3: fMRI-based computational brain mapping to define targets and parameters
This is where Neurotherapeutix’s approach is fundamentally different.
Using fMRI-based computational brain mapping, we calculate the practical treatment plan:
- exact stimulation target (location and depth)
- coil positioning coordinates
- stimulation settings (frequency, intensity, session structure)
Because treatment is based on your individualized connectivity, the plan is not “one-size-fits-all.” It is engineered for repeatability and accuracy.
Step 4: treatment delivery with neuronavigation for consistent targeting
For treatment delivery, Neurotherapeutix uses MRI-based neuronavigation to keep the coil positioned accurately throughout the session.
That means the stimulation is delivered to the intended target, even with small natural head movements, so each session builds consistently on the previous one.
How fMRI-guided TMS therapy differs from standard TMS
Standard TMS is typically based on scalp measurements and generalized anatomical landmarks. That approach can help many people, but it doesn’t account for individual differences in connectivity.
fMRI-guided TMS therapy at Neurotherapeutix is different because it is guided by your own functional brain networks rather than an estimated location.
If you want a deeper comparison, you may also want to read “personalized TMS vs. standard TMS.”
Protocol basics: how stimulation is chosen (excitatory vs inhibitory)
TMS protocols often use frequency to shift activity:
- High-frequency stimulation (>5 Hz) is commonly used to increase activity in underactive regions.
- Low-frequency stimulation (≤1 Hz) is commonly used to reduce overactivity in hyperactive regions.
The goal is not to “turn everything up” or “turn everything down,” but to help networks regain healthy coordination.
What fMRI-guided TMS therapy is designed to support (and why neuroplasticity matters)
The brain is built to adapt. Neuroplasticity is the brain’s ability to strengthen, reorganize, and form new connections in response to experience.
fMRI-guided TMS therapy is used clinically because repeated, targeted stimulation can influence plasticity-related processes.
In research settings, repeated stimulation has been shown to change functional connectivity within brain networks relevant to cognition and emotion, including network-level effects seen in imaging-based studies.
In everyday terms: each session is a small, guided “training signal.” Over time, the brain can begin to run those circuits in a healthier pattern.
Conditions Neurotherapeutix commonly supports with fMRI-guided TMS therapy
Because the treatment is based on connectivity patterns, not just a diagnosis, fMRI-guided TMS therapy may be used to support a range of psychiatric and neurological concerns.
Patients often come to Neurotherapeutix for support with conditions including depression, anxiety, PTSD, ADHD, autism spectrum disorders, and cognitive concerns after injury.

FAQs about how fMRI-guided TMS therapy works
Is fMRI-guided TMS therapy safe for everyone?
fMRI-guided TMS therapy is non-invasive and well-tolerated by many people, but it is not right for everyone. Safety depends on factors like medical history and implanted devices.
Neurotherapeutix evaluates each patient carefully before treatment.
How long does a typical session take?
Most sessions take about 20–30 minutes. Because there is no anesthesia, most patients can return to normal activities right away.
Your treatment schedule may vary based on your individualized plan and clinical goals.
How soon will I notice improvements?
Some patients notice changes (such as improved energy, clearer thinking, or greater emotional steadiness) within the first few weeks, while others notice them later in the series.
Because fMRI-guided TMS therapy is designed to support durable network-level changes, Neurotherapeutix focuses on steady, measurable progress rather than promising a specific timeline.
Can fMRI-guided TMS therapy be combined with other treatments?
Yes. Many patients combine fMRI-guided TMS therapy with psychotherapy, medication management, rehabilitation strategies, and lifestyle support, when appropriate.
If you want coordinated care, Neurotherapeutix also offers full psychiatric services and supportive mental health coaching.
Are there side effects?
Side effects are usually mild and temporary. The most common are scalp discomfort during treatment and occasional headaches. Serious adverse events are uncommon.
How does fMRI-guided TMS therapy differ from standard TMS?
Standard TMS often targets based on scalp measurements and generalized landmarks.
fMRI-guided TMS therapy at Neurotherapeutix uses computational brain mapping to target individualized functional networks.
What questions should I ask before starting fMRI-guided TMS therapy?
Helpful questions may include:
- What exact brain network(s) are you targeting based on my fMRI?
- What symptoms are you tracking, and how will we measure progress?
- How will you adjust the plan if I’m improving slowly or if side effects occur?
- Should any medications be changed during treatment (only with prescribing guidance)?
How is treatment tailored to my individual brain connectivity?
Your therapy is guided by your fMRI results and translated into a stimulation plan using computational brain mapping. Neuronavigation helps ensure the coil returns to the same target area session after session.
That combination (mapping + navigation) is designed to make treatment more consistent and specific than landmark-based stimulation.
Do I need an MRI before I can start?
For Neurotherapeutix’s fMRI-guided TMS therapy approach, yes, because our functional MRI data is used for computational brain mapping and individualized targeting. It’s a key difference between this approach and standard TMS clinics.
What if I’ve already tried a standard TMS and it didn’t work?
Many patients explore fMRI-guided TMS therapy after trying other options.
If standard TMS did not help (or helped only partially), individualized connectivity-based targeting may offer a different path, especially when symptoms are driven by networks that weren’t adequately targeted previously.
A consultation can help clarify whether your history and goals make you a reasonable candidate.
Is fMRI-guided TMS therapy FDA-cleared?
TMS devices are FDA-cleared for certain indications, but “fMRI-guided” targeting is a specialized clinical method built on imaging, computational targeting, and neuronavigation. If you want condition-specific regulatory details for your situation, Neurotherapeutix can walk you through what is FDA-cleared for your diagnosis and what is considered off-label use based on the clinical plan.
