Causal Role of Delta and Theta Oscillations in Hierarchical Cognitive Control
Completed · Not applicable
Conditions studied: Rhythmic Transcranial Magnetic Stimulation (rTMS) Effect on Hierarchical Cognitive Control
In brief
The purpose of this clinical trial is to evaluate the effect of rhythmic transcranial magnetic stimulation (TMS) delivered at delta (2.2 Hz) or theta (6.5 Hz) frequency on cognitive control. This study aims to explore how targeted stimulation at delta and theta frequencies modulates brain activity to enhance cognitive performance in healthy populations.
