Figure 1From: Different patterns of cortical excitability in major depression and vascular depression: a transcranial magnetic stimulation study MEP amplitudes at different ISIs from the 3 groups with respect to the hemisphere. Data are expressed as mean ± SE. (whiskers). VD = vascular depression; MD = major depression; C = Controls; MEP = Motor Evoked Potential; ISI = Interstimulus Interval.Back to article page
