The Body & Space Team conducts research in the field of body representation, body action and space representation. In order to interact successfully with our spatial environment, our body internal representation must be flexible enough for coping with postural changes, morphological body changes, and physical or neurological injuries. For the same reason, we build an internal model of gravity that can equally be challenged. Finally, our interaction with our spatial environment, through physical or simulated body actions, shapes the way we perceive it.
The strength of the Body & Space Team is to embrace these intimately linked aspects in healthy and neurologically injured patients with a translational approach, that is, for the purpose of both fundamental and applied issues. Its originality comes from its strong links with the medical world, due in particular, to the presence in the team of members from the Army Biomedical Research Institute (IRBA) and the Department of Neuro-rehabilitation, University Hospital Grenoble (UGA-CHU).
The methods used by our team to tackle these different facets of body representation, body action and space representation are diversified and exploit all the facilities offered by the Grenoble-Chambery psychology-neuroscience ecosystem going from behavioral experiments (with virtual reality, postural platforms and parabolic flights for instance), to brain imagery (EEG, IRMf), neuromodulation (TMS, tACS) experiments and rehabilitation programs.

• Axis 1 : Body and Movement perception : The first axis of the team project is related to the sense of movement and multisensory integration processes. It is approached from behavioral, computational and neural perspectives.

• Axis 2 : Sensory-motor adaptation and space perception : We aim to understand the mechanisms underlying the neurophysiological and cognitive aspects of the links between perception and action. We specifically investigate the flexibility and plasticity of sensorimotor mechanisms and the top-down influences of motor programming, attentional and emotional processes in sensorimotor plasticity.

• Axis 3 : Verticality representation shapes action in gravity : We aim to investigate the internal model of verticality with a two-way translational approach : 1) basic research using healthy subjects exposed to peculiar hypo- or hyper-gravity conditions or patients with specific alterations of central nervous system (stroke, Parkinson disease etc.) ; 2) improvement of clinical evaluation and rehabilitation of motor activities.

This team is composed of nine permanent staff and two associate (*) members.
