Identify the Optimal TMS Pulse Protocol to Modulate Reward Activity
What this study is about
The primary goal will be to identify the optimal pulse protocol by systematically measuring the effectiveness of various theta burst stimulation and repetitive rTMS protocols to increase and decrease the reward positivity in dependent smokers. The secondary objective will be to measure the protocols' effectiveness to increase decision-making capacity using the probabilistic selection task (PST).
View original scientific description
The primary goal will be to identify the optimal pulse protocol by systematically measuring the efficacy of various theta burst stimulation and repetitive rTMS protocols to increase and decrease the reward positivity in dependent smokers. The secondary objective will be to measure the protocols' effectiveness to increase decision-making capacity using the probabilistic selection task (PST). The third objective will be to specifically assess whether the TMS targets has a differential impact on state levels of craving relative to baseline (Tobacco Craving Questionnaire \[TCQ\]. The investigators plan to accomplish these three objectives using a randomized, controlled experiment involving 2 sessions.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Exclusion criteria
- Contraindication to MRI (e.g., presence of metal in the skull, orbits or intracranial cavity, claustrophobia).
- Contraindication to rTMS (history of neurological disorder or seizure, increased intracranial pressure, brain surgery, or head trauma with loss of consciousness for \> 15 minutes, implanted electronic device, metal in the head, or pregnancy).
- History of autoimmune, endocrine, viral, or vascular disorder affecting the brain.
- History or MRI evidence of neurological disorder that would lead to local or diffuse brain lesions or significant physical impairment.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
