Understanding the vestibular perception

The primary aim of the In-Vest project is to offer a better understanding of how self-motion perception works. To do so, our team uses the stimulation of the vestibular apparatus, responsible for the perception of self-motion, coupled with brain imaging techniques, in order to map the cerebral activations related to the perception of self-motion and to define how they are integrated with visual information.



Centre de Recherche Cerveau et Cognition (CerCo)

The CerCo is a joint CNRS/Paul Sabatier University – Toulouse III unit. The scientific objectives of the CerCo are focused on the study of different sensory modalities and their integration, cognitive functions such as memory, object recognition but also consciousness and mental states.

Cognition, langues, langage, Ergonomie (CLLE)

The CLLE laboratory is a multidisciplinary research unit in the field of Cognitive Sciences: its work covers the fields of linguistics, psychology, computer science, philosophy, education and neuroscience. Since January 2021, the laboratory has implemented a new structure.

Vertige Extrême

Studies of the adaptation capacities of human beings in real life conditions in constraining environments, according to chronobiological, sensory and emotional criteria. Determination of physiological and sensory markers of adaptation and application to the health field.


  • What are the optimal vestibular stimuli to evoke a consistent and realistic vection, self-motion illusion?
  • What are the underlying cortical networks?
  • How is gravity involved in these processes?
  • How aging affects self-motion perception?
  • Is there a specificity of the human vestibular system compared to that of non-human primates?


For a scientific matter of this scale, it is necessary to have a team adapted to the project in terms of skills. The In-Vest project brings together experts in the various fields to be involved in order to provide comprehensive results and a better understanding of the mechanisms involved in visuo-vestibular integration in primates.
