      abstract     = {The mechanisms driving cortical plasticity in response to
                      brain stimulation are still incompletely understood. We here
                      explored whether neural activity and connectivity in the
                      motor system relate to the magnitude of cortical plasticity
                      induced by repetitive transcranial magnetic stimulation
                      (rTMS). Twelve right-handed volunteers underwent functional
                      magnetic resonance imaging during rest and while performing
                      a simple hand motor task. Resting-state functional
                      connectivity, task-induced activation, and task-related
                      effective connectivity were assessed for a network of key
                      motor areas. We then investigated the effects of
                      intermittent theta-burst stimulation (iTBS) on motor-evoked
                      potentials (MEP) for up to 25 min after stimulation over
                      left primary motor cortex (M1) or parieto-occipital vertex
                      (for control). ITBS-induced increases in MEP amplitudes
                      correlated negatively with movement-related fMRI activity in
                      left M1. Control iTBS had no effect on M1 excitability.
                      Subjects with better response to M1-iTBS featured stronger
                      preinterventional effective connectivity between left
                      premotor areas and left M1. In contrast, resting-state
                      connectivity did not predict iTBS aftereffects.
                      Plasticity-related changes in M1 following brain stimulation
                      seem to depend not only on local factors but also on
                      interconnected brain regions. Predominantly
                      activity-dependent properties of the cortical motor system
                      are indicative of excitability changes following induction
                      of cortical plasticity with rTMS},
