Amplitudes of motor evoked potentials have been normalized to baseline. Error
bars are standard deviation.
Note, continuous theta burst stimulation is thought to induce a suppression of
cortical excitability. Therefore, a larger decrease in motor evoked potential
amplitude provides indication of greater plasticity. Data points below the
dashed black line indicate motor evoked potential suppression.
cTBS, continuous theta burst stimulation; MEP, motor evoked potential.
