What this trial studies

This study investigates how transcranial magnetic stimulation (TMS) can influence cognitive functions such as attention, learning, and memory. Participants will engage in cognitive tasks while receiving either active or sham TMS to determine the optimal design parameters for measuring TMS effects on cognition. The study aims to resolve methodological issues related to task design in TMS research, using a factorial design to identify the best combination of task and TMS settings for reliable behavioral outcomes.
