Research theme

A Varela-inspired approach implies that a brain model should not display an input-outut, nor a sensori-motor, nor a perception-action scheme. By contrast, the brain is embodied within a body delimited by its skin, eyes, ears... This embodiement let the brain to be an autopoietic system that enacts with its environment. The system must maintain or reach desired states, such as survival, pleasure ... despite any perturbations.

   Learning processes of a goal-directed movement involves plasticities in various brain structures. In order to understand how these plasticities may cooperate, we developed a model of the cortico (cerebral cortex) - subcortical (cerebellar cortex and basal ganglia) plasticity interactions during arm movement learning.

   Here, the embodied brain structures try to attain the dopaminergic-reinforced pleasure of maintaining, as long as possible, the unstable equilibrium of an inverted pendulum. This problem was chosen since it has already been addressed by many methods.
