High-resolution prosthetic hearing with a soft auditory brainstem implant in macaques

Stéphanie Lacour, Jocelyne Bloch, Ivan Furfaro, Florent-Valéry Coen, Alix Esther Anne Trouillet, Emilie Cornelia Maria Revol, Laurine Kolly, Florian Dylan Fallegger

Individuals with compromised cochlear nerves are ineligible for cochlear implants and instead rely on auditory brainstem implants (ABIs). Most users of ABIs experience sound awareness, which aids in lip reading, yet not speech intelligibility. Here we engi ...

Sensitivity to Pulse Rate and Amplitude Modulation in an Animal Model of the Auditory Brainstem Implant (ABI)

Stéphanie Lacour, Florent-Valéry Coen

The auditory brainstem implant (ABI) is an auditory neuroprosthesis that provides hearing by electrically stimulating the cochlear nucleus (CN) of the brainstem. Our previous study (McInturff et al., 2022) showed that single-pulse stimulation of the dorsal ...

A low-profile electromechanical packaging system for soft-to-flexible bioelectronic interfaces

Stéphanie Lacour, Giuseppe Schiavone, Florent-Valéry Coen, Alix Esther Anne Trouillet, Florian Dylan Fallegger

Interfacing the human body with the next generation of electronics requires technological advancement in designing and producing bioelectronic circuits. These circuits must integrate electrical functionality while simultaneously addressing limitations in m ...

Conformable neural interfaces : from engineering stretchability at the micro-scale to translational applications

Florent-Valéry Coen

Recently, flexible and soft bioelectronic interfaces have been proposed as a solution to improve existing neural interfaces that currently present mechanical mismatch with the soft tissue. These are devices fabricated with thin polymeric or elastomeric bac ...

Comparison of Responses to DCN vs. VCN Stimulation in a Mouse Model of the Auditory Brainstem Implant (ABI)

Stéphanie Lacour, Florent-Valéry Coen, Nicolas Vachicouras

The auditory brainstem implant (ABI) is an auditory neuroprosthesis that provides hearing to deaf patients by electrically stimulating the cochlear nucleus (CN) of the brainstem. Whether such stimulation activates one or the other of the CN's two major sub ...

Preclinical upper limb neurorobotic platform to assess, rehabilitate, and develop therapies

Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Quentin Barraud, Nicholas David James, Florent-Valéry Coen, Selin Anil, Newton Cho

Numerous neurorehabilitative, neuroprosthetic, and repair interventions aim to address the consequences of upper limb impairments after neurological disorders. Although these therapies target widely different mechanisms, they share the common need for a pr ...
