The electrodes that we're putting in are on the size scale of like 50 microns, right? And that's big for something that goes into the brain. If you have a neuron within about 30 microns, you can see the little check marks every time it fires a spike on your signal. Scar tissue pushes that away; if I grow a scar around that electrode, those neurons get farther away. That's the hardest thing about making these systems. What you know, my lab and others are doing to try to get around that problem is we're making wires that are smaller than neurons,. So my lab uses carbon fiber. Carbon fiber is one of the strongest materials we have access to as
