Identify the Optimal TMS Pulse Protocol to Modulate Reward Activity
Determining the Optimal Pulse Protocol for TMS Induced Change in Reward Positivity
Rutgers, The State University of New Jersey
42 participants
Aug 1, 2024
INTERVENTIONAL
Conditions
Summary
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.
Eligibility

Interventions
TMS will be delivered using a robotic neuronavigation system (Smartmove, ANT). Stimulation intensity will be standardized. Stimulation will be delivered to the L-DLPFC using a active/placebo figure-8 coil and a magventure TMS device.
