Stephen Ryu, a neurosurgeon and key figure in the Stanford Neuroprosthetics Lab joins Tjaša Zajc on Faces of Digital Health to demystify brain–computer interfaces (BCIs): how they work, why invasive systems outperform non-invasive ones, realistic use cases (motor control and speech), timelines and durability, safety and MRI trade-offs, cybersecurity, business models, and what Paradromics is building as a high-bandwidth BCI platform.

Throughout, Stephen separates science fact from sci-fi, stressing near-term potential to restore communication and movement for people living with paralysis, while noting earlier-stage areas like mental health and pain.
