Optimizing TMS Pulse Protocols for Reward Processing in Smokers

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to identify the most effective transcranial magnetic stimulation (TMS) pulse protocols to modulate reward activity in nicotine-dependent individuals. It will involve a randomized controlled design with two sessions, where participants will receive either excitatory or inhibitory TMS protocols while engaging in decision-making tasks. The study will also assess the impact of these protocols on craving levels and decision-making capacity. Participants will be required to abstain from smoking for four hours prior to each session to ensure accurate measurement of outcomes.

Why it matters

2. 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).
3. History of autoimmune, endocrine, viral, or vascular disorder affecting the brain.
4. History or MRI evidence of neurological disorder that would lead to local or diffuse brain lesions or significant physical impairment.
