Clinical Trial Summary

The purpose of this study is to help understand how attention processes influence brain engagement during emotion and social cognition. The investigators also want to know if these processes are associated with drinking alcohol. Participation includes three study visits of about 2 hours each over approximately a month. The first visit involves a magnetic resonance imaging (MRI) scan and answering survey questions. Each of the next two visits will involve a session of transcranial magnetic stimulation (TMS, a non-invasive brain stimulation technique) followed by another MRI scan. People in the Auburn/Opelika area 19 or older are eligible to participate. People who drink alcohol and people who do not drink or don't drink very much are invited to participate.

Eligibility

Inclusion Criteria:
