Paradromics reports four-year neural recording durability in sheep
Published in Brain Activity, Brain/Neurology, Tech News, Tools.
October 9, 2026 — In an October 8 update, Paradromics reported more than four years of stable neural recording and decoding performance in two sheep implanted with cortical modules representative of the electrode technology used in its Connexus brain-computer interface.
The company states that both animals remained healthy, electrode arrays did not migrate, and neural spike signal-to-noise ratios remained stable. A separate ongoing study involving six sheep and the complete platform reportedly maintained stable signal-to-noise ratios for nearly two years.
These are preclinical durability observations. They do not establish four-year safety or communication performance in people, and the small animal cohorts limit how broadly the results can be generalized.
Paradromics is continuing long-term follow-up while advancing the Connect-One early feasibility study in humans. Connexus remains an investigational device.
Implant durability is a relevant engineering question because loss of recording quality or device failure could require additional procedures. The update supports further investigation of sustained neural interfaces without resolving their long-term human performance.
