简要总结
The study will examine whether the benefits of brain stimulation on mental functioning can be enhanced if an individual is actively engaging the target brain networks while receiving brain stimulation. The study includes two separate sessions and people will complete either a cognitive task or a perceptual task while receiving transcranial magnetic stimulation. The study will measure change in brain function with EEG.

结局指标
主要结局
Theta-gamma cross frequency coupling
时间窗: 0-500 ms after each TMS stimulus
A metric of brain function measured with EEG - the coupling of theta oscillation phase with gamma power. This will be measured immediately following the intervention (TMS stimulation).
Cortical excitability
时间窗: 60-300 ms after each TMS stimulus
TMS-evoked potentials will be measured with EEG to examine cortical excitability after TMS. This will be measured immediately following the intervention (TMS stimulation).
