Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy right-handed individuals aged 18 to 35 with normal or corrected-to-normal vision.
✕Probably not a fit
Patients with neurological disorders, a history of seizures, or those currently receiving treatment for ADHD/ADD may not benefit from this study.

What this trial studies
This clinical trial evaluates how rhythmic transcranial magnetic stimulation (TMS) at delta and theta frequencies affects cognitive control in healthy individuals. The study involves two tasks designed to assess hierarchical cognitive control, where participants respond to stimuli based on memorized rules and feature comparisons. By modulating neural oscillations through targeted stimulation, the research aims to enhance cognitive performance and understand the underlying neural mechanisms involved in cognitive tasks.
Why it matters
Potential benefit: If successful, this study could lead to new non-invasive methods for enhancing cognitive performance in healthy individuals.
How similar studies have gone: Previous studies have shown that rhythmic TMS can effectively modulate neural oscillations, suggesting potential success for this approach.
