Brief summary

This study has two main goals : * to investigate the impact of aging on cortical excitability (CE) * to investigate the impact of state dependency on CE, using a cognitive task and an emotional one. A Neuronavigation system of transcranial magnetic stimulation is used, and electromyographic response are recorded.

Design outcomes

Primary

MeasureTime frameDescription
Amplitudes of Motor evoked Potentials (µV) for ICI and ICF.Participants will be followed for an expected average of one monthMotor Evoked Potential (MEP) from the first dorsal interosseous are register during the stimulations. Intracortical Inhibition (ICI) and Facilitation (ICF) are a paired-pulse TMS measure of cortical excitability. A short Interval interstimuli (2ms) leads to a cortical inhibition, which reflects the GABAergic neurotransmission; whereas a longer interval interstimuli leads to a cortical facilitation, which reflects glutamatergic neurotransmission.
Durations of Cortical Silent Period (ms)Participants will be followed for an expected average of one monthCortical Silent Period (CSP) is a single-pulse TMS measure of cortical inhibition, stimulations are applied while subjects are exerting a muscular contraction of the thum-index pinch and lead to a muscular cancellation. Duration of this silence is measured.
