**Clinical Trial Summary: Inhibitory Control: Effects of Modulation**

This clinical trial is looking at how certain brain networks involved in controlling our impulses work in healthy young adults. Impulse control is important for managing various conditions like substance abuse, obsessive-compulsive disorder, and attention-deficit hyperactivity disorder. The researchers aim to use a technique called neuromodulation to see if they can improve how these brain networks function and, in turn, enhance performance on tasks that require good impulse control. By understanding these brain mechanisms better, the hope is to improve treatments for people who struggle with impulse control issues.

If you are a healthy young adult aged 18 to 35 and are fluent in English, you might be eligible to participate in this study. Participants will be grouped based on their impulse control abilities, as measured by a specific test. However, if you have certain medical conditions, a history of seizures, or are currently taking psychiatric medications, you may not be able to join. Those who participate can expect to undergo various assessments, including an MRI, and to engage in tasks designed to test their impulse control. This study could contribute to meaningful advancements in how we treat impulse control disorders in the future.
