BCIwiki (bciwiki.com) — According to a paper published by Journal of Neural Engineering, Guo L published a perspective on 2026-10-14 introducing Cybertissue Neuroprosthetics (CN). The concept treats a neural implant as a functional tissue device composed of living cells, aiming for structural and functional integration with the host nervous system rather than relying solely on a traditional electrode interface.
The paper describes chronic foreign-body reactions and fibrotic encapsulation as processes that progressively damage the electrode-tissue interface, deteriorate signals, and can eventually cause device failure. The author argues that improvements in material biocompatibility, mechanical matching, and implant surfaces have advanced the field without resolving the fundamental challenge of long-term implant stability.
Under the CN concept, living cells form the implant's foundation, optionally augmented with minimal nanoelectronics, nanomaterials, or genetic modifications. The author proposes reducing or eliminating foreign materials and leveraging the brain's cellular signaling mechanisms to pursue long-term neuromodulation and information exchange. The paper brings emerging directions, from engineered cybercells to transplantable living devices, into this conceptual framework.
The author presents biological integration, self-sustaining operation, and lifetime use as potential goals. This perspective introduces a concept and research opportunities; it does not establish that CN implants have achieved lifetime stability or provide clinical validation of their safety or effectiveness.
