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 ...
