Experimental Timeline.

<p>Participants (N = 27) completed four separate scanning sessions. (<b>A</b>) The first session was used to acquire baseline BOLD and ASL fMRI measures, a high-resolution anatomical MRI scan, and resting motor thresholds using EMG. (<b>B</b>) The remaining three fMRI scans began with the collection of pre-TBS BOLD and ASL scans. These were followed by 40 s of theta-burst TMS to one of three target locations (L dlPFC, L aI/fO, or L S1). Following TBS, two BOLD and two ASL scans were collected in an interleaved fashion.
