TK (Takashi DY) Kozai @bioniclab.bsky.social · May 24 🧱 Your brain implant isn't failing at the electrode. It's failing in the blood vessels. The BCI field spent decades on scar tissue and coating chemistry. Our data point 50-100 microns away, inside vessels nobody was monitoring. 🧵

🔬 Capillaries feed neurons. Wrapped around them are pericytes and smooth muscle cells, biological valves that open and close to route fuel where it's needed. When an electrode goes in, pericytes near the device constrict, squeezing capillaries shut. Blood flow drops.
