  1. Key: MEP, motor evoked potential; MNS, median nerve stimulation; MT, motor threshold.
  2. 1 Conditioning intensity for median nerve stimulation (MNS).
  3. *Significant difference at adjusted p-values (p = 0.0125) for multiple comparisons (see [33] for a more elaborate analysis of these age differences)
