All participants compared in (A), older participants divided by ipsilateral Motor Evoked Potentials (iMEPs) response in (B). All values were compared with the Student’s t-test, except categorical measures of gender and handedness indicated with F which were compared with Fisher’s exact test. Bold indicates significant values (p < 0.05).
