Our aim was to combine transcranial-magnetic stimulation
and resting-state (RS) fMRI to investigate changes in
functional connectivity at rest induced by prefrontal
continuous theta-burst stimulation (cTBS). Seed-based
analysis was used to identify the main connections to
the prefrontal cortex. The adjacency matrix summarising
the correlation between the resulting 29 regions was
computed before and after cTBS, and compared using the
Network Based Statistics toolbox. After cTBS,
thecorrelation between the right prefrontal cortex and
right parietal cortex was decreased, demonstrating for
the firts time the possibility to induce selective
changes in a specific region without interfering with
functionally correlated area.
