Réactivité visuo-manuelle, Contrôle du geste et Expertise sensorimotrice: étude en IRM fonctionnelle événementielle.

Abstract : This study aims to identify the neural network involved in the intentional visuo-manual control and to explore behavioural and functional effects of a long term practice of sports, as fencing. The double step paradigm adapted to event-related fMRI study shows that intentional trajectory corrections conduct to an over-activation of the cerebral network underlying visuo-manual control (including occipital visual areas, parietal areas, frontal motor, premotor and oculomotor areas, thalamus, basal ganglia and the cerebellum). Fencers' visuomanual performances rely more on the associative and executive cerebral areas while control subjects' performances recruit more the visual areas. The visuomanual control relies on neural loop underlying operational modules gradually recruited related to the behavioural and environmental constraints. Sensorimotor expertise related to practice of sport can conduct to modify cerebral functional map.
