Multisensory Body and Space Representations (BASES-EXTINCTION)

Not Applicable

• Conditions: Blindness; Healthy

• Registration Number: NCT03201341
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

To accurately control body movements to interact with objects, our brain needs representations of the body and the nearby space. The broader aim of this research project is to study the behavioural and physiological mechanisms involved in the constitution of these representations, to identify their neural bases, in order to better understand the dysfunctions in the context of neurological or developmental disorders.
