Official title
Frontal E/I Balance Mediation of tACS Effects on Behavioral Flexibility
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to learn whether a single non-invasive brain stimulation alpha-transcranial alternating current stimulation (alpha-tACS) session changes measures of excitability in the prefrontal cortex. It will also learn whether these changes predict differences in habitual action selection in a laboratory task and whether the effects depend on alcohol use history. The main questions it aims to answer are: Does alpha-tACS reduce habitual action selection by reducing excitability in the prefrontal cortex? Is alpha-tACS most effective in reducing habitual action selection in hazardous drinkers who engaged in binge-drinking during adolescence? Researchers will compare alpha-tACS to sham stimulation to see if alpha-tACS changes habitual action selection by changing prefrontal excitability. Participants will: Visit the lab for behavioral training Visit the imaging center for an MRI session Visit the lab to receive alpha-tACS or sham stimulation during behavioral testing and undergo EEG recordings before and after stimulation Visit the imaging center for a repeat MRI session Provide a small sample of blood from a finger-prick in the first and last visits.
