Episode notes
Invasiveness vs. Signal Quality
- More invasive brain implants capture stronger signals but entail deeper brain penetration and surgery risks.
- Less invasive devices reduce surgical risks but provide less precise brain interaction.
Trade-offs of Implant Approach
- Less invasive brain-computer implants retrieve signals remotely and may be removable/upgradable.
- More invasive implants permit direct and precise neural control, such as moving a cursor or prosthetic.
Synchron's Less Invasive BCI Method
- Synchron uses a wire through blood vessels to place electrodes in your brain's vessels, avoiding skull drilling.
- Apple partners with Synchron so users can control objects with eye movement and major thought actions like clicking.
