Un certain nombre de signaux sensoriels transmet de l'information sur la position et les mouvements de notre corps (e.g. visuel, proprioceptif, cutané et vestibulaire). En fonction des mouvements et du contexte dans lequel ils sont réalisés, l'information transmise par ces signaux peut être pondérée (facilitée ou supprimée). Notre objectif est de comprendre les mécanismes impliqués dans le traitement de cette information multimodale pendant la planification et l'exécution de mouvements comme l'initiation de la locomotion.
Several sensory signals provide information on the position and motion of body segments (e.g. visual, proprioceptive, cutaneous and vestibular). Depending of the movements and of the context in which they are produced, the information provided by these signals can be re-weighted (facilitated or suppressed). The goal of our studies is to understand the mecanisms underlying the processing of these multimodal sensory information during the planning and execution stages of movements such as when initiating locomotion.
