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

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

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 ...
