NCT03167931

Brief Summary

The main objective of this study is to estimate the effect of the neuromodulation on the behavioral performances during the access in semantics according to the age of the individuals. Neuromodulation by non-invasive stimulation allows to explore the functioning of the brain by exciting or by inhibiting localized cortical zones. The modulation of the performances in cognitive tasks, further to the neuromodulation of these zones, allows to deduce on their functional roles.

Outcome Measures

Primary Outcomes (1)

  • Effect of the neuromodulation on the behavioral performances during the access in semantics

    Evaluation of the changes of the behavioral performances before and after the neuromodulation by non-invasive cortical stimulation according to the age. More exactly, the investigators shall compare response times before and after neuromodulation between both age groups (18-49 years and 50-85 years), by testing the interaction between the effect of the neuromodulation and the age.

    3 hours

Secondary Outcomes (5)

  • Estimate the effect of the neuromodulation on the behavioral performances

    3 hours

  • Estimate the effect of transcranial Electrical Stimulation (tES) on the cognitive performances by neuropsychological scores, according to the age.

    3 hours

  • Estimate the effect of tES on the cerebral functional activity, by comparing blood-oxygen-level dependent (BOLD ) signal or functional MRI before and after tES according to the age (18-49 years vs 50-85 years).

    3 hours

  • Estimate the effect of the Transcranial Magnetic Stimulation (TMS) on the cognitive performances by neuropsychological scores, according to the age.

    3 hours

  • Estimate the effect of the TMS on the intellectual functional activity, according to the age.
