Brain Stimulation Effects on Cognitive Task Performance

This study is looking at how a non-invasive brain stimulation method called Transcranial Magnetic Stimulation (TMS) affects thinking abilities. TMS uses magnetic fields to influence brain activity. Researchers want to find the best ways to design tasks to measure how TMS impacts attention, learning, and memory. You might be able to join if you are 18 to 65 years old, right-handed, and fluent in English. People with a history of seizures, certain medical conditions, or head injuries cannot participate. The study will measure your accuracy and reaction time on a memory task to see the effects of TMS. The current status of this study is unclear.

Study design
This is an interventional study with a planned enrollment of 100 participants. It uses a factorial design to test different combinations of tasks and TMS settings.
What's involved
You will have a single study appointment lasting 1 hour, where you will complete cognitive tasks while receiving either active or sham (non-stimulating) TMS.
Compensation
Not stated in the trial record.
Follow-up
There will be no follow-up after your single study appointment.
