Main lines of research

  • Motor system

    Based on the plasticity of the nervous system, a certain degree of spontaneous functional recovery may take place post-lesion. The goal of our work in non-human primates is first to elucidate mechanisms involved in such spontaneous functional recovery following spinal cord lesion, motor cortex lesion or Parkinson disease. Second, in the context of translational medicine, different promising therapeutic strategies are tested with the goal to enhance the spontaneous functional recovery:

    Neutralization of neurite growth inhibitors: anti-Nogo-A antibody treatment.

    Cellular therapy: see  "autotransplantation" for details

  • Multisensory integration

    Multisensory processes are widespread in the brain and integrate information from more senses than once thought. However, the underlying mechanisms contributing to organization for action are still unclear. Therefore investigating impaired functions like (1), (2) and (3) is one of the possible ways to highlight key steps in multisensory processing. Along with such interests, our research projects examine also how attention modulates multisensory processes and how it is influenced by training in a rehabilitative perspective.
