Outcome Measures

Primary Outcomes (1)

  • miRNA expression profile in plasma of healthy persons before and after tVNS as compared to before and after sham tVNS

    After 4 hours of VNS

Secondary Outcomes (3)

  • Serum concentrations of different cytokines, chemokines and neuropeptides in healthy persons before and after tVNS as compared to before and after sham tVNS

    After 4 hours of VNS

  • Differences in cerebral microstructural (DTI-MRI) and functional (resting state network, fMR) between tVNS group and control group

    After 4 hours of VNS

  • Differences in gastric motility between tVNS group and control group

    After 4 hours of VNS
