Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to examine the effects of continuous theta burst stimulation (cTBS) on different forms of cognitive control in adults who smoke cigarettes, and to determine if the location where cTBS is delivered may help smokers reduce or quit smoking. Participation in the study will take 3-weeks over 4 visits, with a total time commitment of approximately 12 hours.

cTBS to Ventrolateral Prefrontal Cortex

Continuous theta-burst stimulation (cTBS), a form of repetitive transcranial magnetic stimulation (rTMS), affects brain areas stimulated directly underneath the scalp and brain areas that are functionally connected. cTBS will be applied to the ventrolateral prefrontal cortex.
