Brief Summary
Purpose: In this study, the investigators will provide causal evidence for the role of alpha and theta oscillations in cognitive control. Participants: Participants must be healthy, between the ages of 18 and 35, right handed, able to provide informed consent, willing to comply with all study procedures, and be available for the duration of the study, speak and understand English. Procedures: Alpha and theta brain oscillations will be measured and then entrained using frequency specific rhythmic TMS during a retrospective cued cognitive control task.

Outcome Measures
Primary Outcomes (3)
Number of Remembered Items
Participants make a button press on a keyboard to indicate if the probed items are matched or non-matched to the items held in memory after a retrospective cue is presented. The investigators calculate the percent correct for non-match conditions, defined as the hit rate, and the percent incorrect for match conditions, defined as the false alarm rate. 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. For TMS to frontal cortex, working memory capacity is reported when the participant was cued to the right. For TMS to parietal cortex, working memory capacity is reported when the participant was cued to the left.
1 week
Amplitude of Neural Oscillations
The electrical activity of the brain is recorded during performance of the task and brain stimulation. The investigators will perform Morlet wavelet convolution on the recorded electrical signal to calculate the amplitude of neural oscillations in the frequency bands: theta (4-7 hertz) and alpha (8-12 hertz). The amplitude of neural oscillations is reported during the second half of stimulation in the region that is being stimulated. The amplitude is normalized for each participant as the percent change from the amplitude during the baseline period (before the task begins). For TMS to frontal cortex the amplitude of theta oscillations are reported and for TMS to parietal cortex the amplitude of alpha oscillations are reported.
1 week
Response Time
Participants make a button press on a keyboard to indicate if the probe items are matched or non-matched to the items held in memory after a retrospective cue is presented. The investigators will calculate the response time of this choice as the difference between the time of the button press and presentation of the probe. For TMS to frontal cortex, response time is reported when the participant was cued to the right. For TMS to parietal cortex, response time is reported when the participant was cued to the left.

Study Arms (2)
TMS to frontal cortex followed by TMS to parietal cortex
EXPERIMENTALParticipants will receive TMS while performing a cognitive control task. In their first stimulation session, the TMS coil will be placed over the frontal cortex on the scalp. In their second session, the TMS coil will be placed over the parietal cortex on the scalp. During every session, subjects receive Theta TMS, Alpha TMS, and Arrhythmic TMS.

Interventions
TMS will be administered at the frequency of each subject's endogenous theta oscillation (4-7Hz)
TMS will be administered at the frequency of each subject's endogenous alpha oscillation (8-12 Hz)
TMS will be administered arrhythmically; i.e. a sequence of pulses with randomized timing
