Studies were listed according to specific samples and within the groups to stimulation frequency.
HC, healthy controls; TI, tinnitus; AC, auditory cortex; DLPFC, dorsolateral prefrontal cortex; MTG, middle temporal gyrus; STG, superior temporal gyrus; ↑, increases; ↔, no changes; ↓, decreases; CSP, cortical silent period; ICF, intracortical facilitation; MEP, motor evoked potential; RMT, resting motor threshold; SICI, short-interval intracortical inhibition; please note that increases in SICI means increases in inhibition and concomitantly a numeric decrease in the raw data.
