Brief Summary

The goal of this clinical research study is to learn more about whether individual differences in brain responses to emotional triggers impact rTMS (repetitive transcranial magnetic stimulation) responses in people who smoke.

History of brain surgery, implanted electronic device, metal in the head. 17. Cardiac pacemakers, neural stimulators, implantable defibrillator, implanted medication pumps or sensors, intracardiac lines, or acute, unstable cardiac disease, with intracranial implants (e.g., aneurysm clips, shunts, stimulators, cochlear implants, or electrodes) 18. History of or currently under medical care for myocardial infarction, angina, congestive heart failure, cardiomyopathy, stroke, or transient ischemic attack. 19. Reports vision problems that are not treated. 20. Has a hairstyle not compatible with the EEG and unwilling to modify hairstyle (e.g., braids, ponytails, dreadlocks, non-removable hair extensions or wigs, etc.) to accommodate the EGG net that is required to be worn on the scalp during the experimental procedure. 21. Reports current diagnosis or history of type I diabetes. 22. Currently using insulin. 23.
