iTBS aftereffects on cortico-motor excitability. Lack of LTP-like plasticity response after iTBS in MCI, compared with demographically similar HCs. There was a significant effect of iTBS on MEP amplitudes in the HC group which was not present in the MCI group. Pairwise comparisons show that this difference was driven by a significant increase in cortico-motor excitability between at 5 minutes after iTBS in the HC group. Abbreviations: HC, healthy control; iTBS, intermittent theta-burst simulation; LTP, long-term potentiation; MCI, mild cognitive impairment; MEP, motor evoked potential.
