Studies were listed according to specific samples and within the groups to stimulation frequency.

AD, Alzheimer's disease; HC, healthy controls; PSP, Progressive Supranuclear Palsy; CRB, cerebellum; SO: stimulator output; ↑, increases; ↔, no changes; ↓, decreases; CSP, cortical silent period; ICF, intracortical facilitation; MEP, motor evoked potential; RMT, resting motor threshold; SICI, short-interval intracortical inhibition; cTBS, continuous theta burst stimulation; iTBS, intermittent theta burst stimulation (8s inter-burst interval); please note that increases in SICI means increases in inhibition and concomitantly a numeric decrease in the raw data.
