🦯 The Cells Nobody Was Watching
BCI research focus almost entirely on neurons. Makes sense, BCIs read & write neural activity. Everything else (most of brain cells) was treated as mere background infrastructure. That framing was wrong… and it cost the field decades. #BCI #NeuroTech #Neuroscience

To ChatGPT: Elon Musk focuses on scalable technologies, also for the upcoming Neuralink Blindsight brain implant for the blind. At some point these implants will start to fail in patients. Will Neuralink's handling of failing brain implant prove scalable? […]

I don’t say this nearly enough on here, but I’m so grateful for my team. They’re some of the hardest working, brilliant folks on the planet. Whether they’re pushing the needle on first-in-human #BCI tech, helping folks with diagnoses like #LongCOVID, #MECFS and chronic #lyme

If we want BCIs that can last a lifetime in the human brain, we need to fund the science that explains why they currently don’t. Link to basicscience resources:

🛣️BCIs will run out of runway.
“Discovery. That’s what this is used for.” -West Wing
BCIs are having a moment: billions in private capital, paralyzed patients moving cursors and typing with their minds. Real progress by talented engineers.
But most people don’t see what’s underneath. #BCI #Neurotech

Brown glass on brown wooden table top, with insets showing AI depth map view in The vOICe for Android.
Visual prostheses (brain implants, retinal implants) for the blind typically require high contrast scenes for good results. AI depth mapping with foveal enlargement can help get around that play.google.com/store/apps/details AI depth view toggle […]

🩹 The Brain Tries to Heal Itself Around Neural Implants… And That’s the Problem After the shock of insertion, the brain does what it’s optimized to do over millions of years: heal.
In doing so, it builds a wall around your electrode. #Neuroscience #BCI #Immunology #NeuralEngineering #NeuroTech

Brain tissue is as soft as gelatin.
Most silicon electrodes implanted into it are ~1,000,000x stiffer. That mismatch isn’t a small detail, it’s one of the main reasons BCIs fail over time. #Neurotechnology #BCI #BrainComputerInterface #Neuroscience #MaterialsScience
