Study Summary
The participants will perform a cognitive control task. During the task, rhythmic trains of transcranial magnetic stimulation will be delivered to the prefrontal cortex and parietal cortex. Participants will be screened for their ability to perform the task. Magnetic resonance imaging will be used to localize regions of interest to be targeted. Electroencephalography will be collected concurrent with stimulation.
Primary Outcome
The number of remembered items, often referred to as working memory capacity, is calculated as the number of items to be remembered (2, 3, or 4) times the hit rate minus the false alarm rate, divided by one minus the false alarm rate. The range of values is 0 to 4 where larger values mean better performance.
Interventions
- DEVICE Theta-frequency near-zero phase lag stimulation
- DEVICE Theta-frequency anti-synchrony stimulation
- DEVICE Arrhythmic near-zero phase lag stimulation
- DEVICE Arrhythmic independent stimulation
- DEVICE Alpha-frequency near-zero phase lag stimulation
