The 60-second view
- What problem?
- Daily recalibration makes BCIs impractical outside the lab.
- What did they do?
- Used a 128-channel chronic ECoG implant and let the decoder adapt continuously across sessions instead of resetting each day.
- What changed?
- Performance consolidated into stable 'plug-and-play' control, and new control dimensions could be added over time.
- Why does it matter?
- Stability, more than peak performance, decides whether a BCI is usable day to day.
Method
- Participants
- One person with paralysis
- Interface
- 128-channel chronic electrocorticography implant
- Signal
- Cortical surface field potentials
- Task
- Cursor control across many days
- Decoder
- Long-term closed-loop decoder adaptation
