简要总结

The aim of this study is to investigate whether the anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) in healthy older adults leads to an increase in cortical plasticity (change in motor evoked potentials (MEP) in mV).

结局指标

主要结局

anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) in healthy older adults

时间窗: 1 week

to investigate whether the anodal transcranial direct current stimulation over the primary motor cortex (M1) in healthy older adults increases cortical plasticity (measured via motor evoked potentials)compared to sham stimulation

次要结局

  • Comparison of tDCS-induced changes in the learning success(1 week)
  • Comparison of tDCS-induced changes on central cholinergic activity(1 week)
  • genetic polymorphism, ApoE4(once)
  • MR elastography(1 week)
