[268] Sensory Neuroprostheses for the Restitution of Hearing and Balance


The work of our group focuses on the development of functional rehabilitation tools for patients with sensory deficits of the inner ear (balance and hearing). We are one of the world leaders in the domain, as we have significantly contributed to the development of the multichannel cochlear implant and in recent years the vestibular implant.

Vestibular implant

The highlight of our current research is the development of a vestibular implant, a neuroprosthesis designed to restore vestibular function in patients with a complete bilateral deficit. We have demonstrated the feasibility of the concept in humans, developed surgical techniques for implanting electrodes in contact with the vestibular apparatus, and developed specific electrical stimulation paradigms. Currently, our work focuses on three areas: (a) the evaluation of the actual functional rehabilitation that could be provided to patients by the implant; (b) the study of the critical parameters to optimize performance, and (c) the investigation of the specific contribution of the different sensory modalities involved in balance, since our unique experimental setup allows the de-coupling of the different sources of information (e.g., vestibular and somesthetic/visual information).

Cochlear Implant

The cochlear implant is a very effective tool for the rehabilitation of profound bilateral hearing loss. However, it still does not provide sufficient information in some situations, such as speech perception in noise and sound localization in space. We investigate strategies to improve these aspects. Our goal is to restore an artificial hearing that is as close to normal hearing as possible and to develop a completely implantable neuroprosthesis.
