Episode notes
Neuralink Enables Paralysed Gamer
- Nolan Arbour, paralyzed from the neck down, used Neuralink to control games like Mario Kart with his mind.
- His implant enabled him to move a cursor just by staring at the screen, showing practical use.
Basics of Brain-Computer Interfaces
- Brain computer interfaces let users control digital devices purely with their brain signals.
- They can be wearable or invasive implants requiring brain surgery.
Biological Challenges for Implants
- The body may reject brain implants over time causing device failures like electrode detachment.
- Finding biocompatible materials that conduct electricity well remains a major challenge.
