Our scientific activity is focused on the field of action and representation of action from various adaptative situations during the life span, including pathology and extreme environment such as microgravity. The early action/perception matching, subserving the motor simulation network, is probably a major milestone for the building of action and representation of action during the course of ontogenesis. We have developed a functional approach of motor development based on a gradual mastering of coordination, adaptation and anticipation in postural control in the course of ontogenesis from babies to adolescents. This functional approach is recently associated with studies of brain structures involved in action and representation of action in children and adolescents with typical or atypical neurodevelopment. From our developmental studies, it was possible to put in light two turning points during motor development, such as 6/7 years of age and adolescence. The first step for children consists in building a repertoire of postural strategies. The second step consists in learning to select postural strategy depending on the characteristics of the task and the environmental requirements. An appropriate selection means to anticipate the consequence of the movement in order to maintain balance control and efficiency of the task. Taking into account the complexity of the parameters to control and the late maturation of anticipation and representation of action, it is not surprising that the development of postural control continues up to late periods during childhood and adolescence.
我们的科学活动集中在生命过程中各种适应情境下的动作和动作表现领域，包括病理学和极端环境，如微重力。早期的动作/感知匹配，为运动模拟网络提供服务，可能是在个体发育过程中构建动作和动作表现的主要里程碑。我们已经开发了一种基于协调、适应和在婴儿到青少年的个体发育过程中姿势控制的预测逐步掌握的运动发展的功能方法。这种功能方法最近与儿童和青少年中与动作和动作表现相关的大脑结构研究相关联，这些儿童和青少年的神经发育既有典型的也有非典型的。从我们的发展研究中，可以发现运动发展中有两个转折点，例如 6/7 岁和青春期。孩子们的第一步是建立姿势策略库。第二步是学习根据任务的特点和环境要求选择姿势策略。适当的选择意味着预测运动的后果，以保持平衡控制和任务的效率。考虑到控制参数的复杂性以及预测和动作表现的成熟较晚，姿势控制的发展直到儿童和青少年时期的后期才会结束，这并不奇怪。
