Philip's Brain-Computer Interface Journey
- Philip O'Keefe, with ALS, used an implantable brain-computer interface to regain communication abilities.
- He sent a significant "Hello World" tweet purely by thinking, symbolizing his return to the world through technology.
Blood Vessels as Brain Interface Highways
- Implanting devices directly into the brain triggers immune responses that harm stability.
- Using blood vessels as conduits for sensors avoids this by allowing cells to incorporate the device naturally.
Implantation Procedure Explained
- The brain-computer interface device is implanted via the jugular vein, navigating to the brain's motor cortex.
- The device sits inside the vessel, with a cable that transmits wireless signals, making it invisible externally.
