Once enrolled, this study involves:

• Attending 2-3 experimental sessions
  • Includes clinical interviews, measurement of brain activity using a safe and noninvasive technique called electroencephalography (EEG), brain scanning using magnetic resonance imaging (MRI), and playing simple computer games
• Completing approximately 5 experimental sessions
  • We will apply a form of noninvasive brain stimulation called transcranial alternating current stimulation (tACS)
• Repeating clinical interviews, EEG, MRI, and computer games over the next few weeks for up to three months

If eligible, participants will be compensated $20 per hour for each of the study sessions. 

There is no cost for you to participate in our research study.
