BIONIC: Development of a Patient-Centered BCI Platform

In this joint talk, Dr. Nathan Staff (Neurology) and Dr. Kai Miller (Neurosurgery) present Mayo Clinic’s vision for a patient‑centered brain‑computer interface (BCI) platform designed specifically for people living with ALS, a devastating neurodegenerative disease that progressively removes a patient’s ability to move, speak, and communicate. Dr. Staff describes the urgent unmet need: as ALS advances, patients lose speech, hand movement, and eventually even the ability to use eye‑gaze systems—the only current communication tool for many. The Mayo team aims to create a high‑fidelity, durable, at‑home BCI that restores communication and autonomy by decoding neural signals directly from the brain and linking them seamlessly to existing assistive‑technology ecosystems. Dr. Miller explains the neuroscience and engineering behind this effort, highlighting decades of research in electrocorticography, depth electrodes, broadband neural signals, and operant‑conditioning‑based control. Their approach focuses on stable, scalable neural biomarkers rather than fragile, daily‑retrained algorithms—building a BCI that patients can use independently and reliably in real‑world environments. Together, Staff and Miller outline a future where ALS patients receive early BCI implantation, enabling long‑term communication, environmental control, and quality‑of‑life support—all grounded in a Mayo‑built ecosystem combining neurology, neurosurgery, engineering, cloud data, and patient‑driven design. 00:00 Vision, Recruitment, and the BIONIC Initiative 01:15 Bringing Kai Miller to Mayo Clinic 02:38 Mentorship, Networks, and Building the Right Team 04:05 Setting the Stage for Neuro Innovation 04:23 Lou Gehrig, ALS, and Mayo Clinic History 05:23 What Is ALS?
