Effect of aiTBS on Intrinsic Spectral Dynamics and Task Performance

Aim 1: Measure local shifts in cortical spectral dynamics following aiTBS. Aim 2: Measure network-specific shifts in task performance following aiTBS. Exploratory aim: Evaluate changes to resting state spectral dynamics in absence of stimulation after aiTBS.
