Brief Summary
The purpose of this study is to determine the most effective dose of brief, non-invasive brain stimulation (repetitive transcranial magnetic stimulation, rTMS) for improving cognitive functions such as attention and memory as well as to improve the ability to recover from stressful situations (stress resilience).

Outcome Measures
Primary Outcomes (3)
Mean Score of Neurocognitive Performance (Fluid Cognition)
Participants would complete a computerized batteries (Penn Computerized Neuropsychological Battery and NIH Cognition Battery). Tasks would assess the following domains: information-processing speed, executive function, sustained attention/vigilance, verbal memory, working-memory capacity, inhibition/impulsivity, and sensorimotor function. This composite includes all the tests noted above that are fluid ability measures: Flanker, Dimensional Change Card Sort, Picture Sequence Memory, List Sorting and Pattern Comparison. This composite score is derived by averaging the standard scores of each of the measures, and then deriving standard scores based on this new distribution. Higher values (positive changes from baseline) indicate better performance. The T-score has a mean of 50 in the general population and a SD of 10. Scores higher than the mean indicate better performance.
Baseline (Day 1)
Change From Baseline in Neurocognitive Performance at 1 Week Post Treatment (Fluid Cognition)
Participants would complete a computerized batteries (Penn Computerized Neuropsychological Battery and NIH Cognition Battery). Tasks would assess the following domains: information-processing speed, executive function, sustained attention/vigilance, verbal memory, working-memory capacity, inhibition/impulsivity, and sensorimotor function. This composite includes all the tests noted above that are fluid ability measures: Flanker, Dimensional Change Card Sort, Picture Sequence Memory, List Sorting and Pattern Comparison. This composite score is derived by averaging the standard scores of each of the measures, and then deriving standard scores based on this new distribution. The T-score has a mean of 50 in the general population and a SD of 10. Scores higher than the mean indicate better performance.
Post-treatment (within 1 week of completing rTMS)
Change From Baseline in Neurocognitive Performance at 1 Month Post Treatment (Fluid Cognition)
