Evaluation of the Impact of Laterality on Cerebral Activation During a Motor Task of the Upper Limb in Healthy Subjects

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.
