The Takeaway
Current cochlear implants rely on silicon chips to process audio, which is often a clunky translation for the human brain. This biohybrid system uses actual lab grown brain tissue to encode acoustic waveforms into electrical signals the auditory cortex can understand. The AI driven organoid learns to mimic the brain's natural response to different frequencies of sound. This could provide a much more natural and high fidelity hearing experience for patients who don't benefit from traditional implants.
From the abstract
Current auditory prosthetics, like cochlear implants, are limited by non-physiological signal processing and the use of fixed patterns of electrical stimulation, which restricts spectral fidelity as well as adaptation by the user. We propose a conceptual biohybrid neural interface, the Bone Neuro Bridge (BNB), that seeks to overcome these limitations through an architecture integrating biological processing and intrinsic neural plasticity. The architecture described for BNB has organoid that is
