NCT05428917

Brief Summary

The aim of this study is to investigate the differences in brain activation in healthy subjects during motor tasks, depending on the laterality of the subject, the laterality of the task and the complexity of the task. It seems that the laterality of activation is less marked in left-handed people, when using the non-dominant hand and when performing a complex task. The objective of this study is to highlight profiles of subject and modality of use of the hand with a specific lateralization of cerebral activation.

Outcome Measures

Primary Outcomes (1)

  • Laterality index using t values

    Compare the asymmetry of activation of the sensorimotor cortex during a complex motor task on the dominant side between right-handers and left-handers.

    Minutes 25

Secondary Outcomes (2)

  • concentration of oxyhemoglobin measured with fnirs device

    Minutes 25

  • concentration of deoxyhemoglobin measured with fnirs device

    minutes 25

Study Arms (1)

Near infrared spectroscopy

EXPERIMENTAL

This method allows (like fMRI) to study cerebral neurovascular coupling. It is based on the fact that an activated brain region increases its local blood flow. Oxygenated (HbO) and deoxygenated (HbR) hemoglobin absorb infrared light and it is then possible to identify the cerebral cortical regions involved in a given task. This technique therefore makes it possible to study cerebral activation under more ecological conditions than fMRI and is thus particularly suitable for exploring rehabilitation techniques.

Behavioral: Simple taskBehavioral: complex task

Interventions

Simple taskBEHAVIORAL

The subject is seated on a chair facing a table, both hands resting on the table. The subject is asked, for each block of 20 seconds, to perform flexion / extension movements of the fingers of the left hand at 0.5 Hz.

Near infrared spectroscopy
complex taskBEHAVIORAL

The subject is seated on a chair facing a table, both hands resting on the table. The subject is asked, for each block of 20 seconds, to perform an exercise based on the nine hole peg test
