Figure 4.

Alteration of cortical excitability parameters at day 11. x axis: Tinnitus scores on day 11 compared with day 1 (Negative values correspond to a reduction in tinnitus severity); y axis: a) Changes of the cortical silent period (CSP), b) intracortical inhibition (ISI 2–5 ms) and c) intracortical facilitation (ISI 7–20 ms) relative to baseline. Negative scores for inhibition correspond to an increase in intracortical inhibition. Reduction of the tinnitus score after active rTMS treatment is accompanied by a prolongation of the silent period, an increase in intracortical inhibition and an increase in intracortical facilitation.
