BCI Atlas

BrainGate is a long-running multi-institution intracortical BCI effort (Brown/Stanford/MGH/VA etc.), known for high-performance cursor control and brain-to-text via handwriting.

BrainGate is one of the most important long-running invasive BCI clinical research efforts. Public-facing descriptions emphasize restoring communication, mobility, and independence for people with paralysis.

A landmark result: brain-to-text via attempted handwriting (Nature, 2021)

A widely cited BrainGate-linked demonstration decoded attempted handwriting trajectories from intracortical recordings to produce text at high speed.

A readable overview with some performance numbers:

Why BrainGate matters

If you want to understand what intracortical arrays can do at the “high performance” end, BrainGate is one of the strongest evidence bases.

It’s also a good example of a translational pipeline:

  • carefully run clinical research
  • repeated improvements in decoding methods
  • longer-term attention to usability and at-home use

What to watch

  1. Generalization + daily use How performance holds up across days without re-training.

  2. Scaling channels and stability What hardware stack they use and how signal quality evolves.

  3. Clinical commercialization path How/when these systems become actual products.


Notes on sourcing

Draft. We should add additional peer-reviewed BrainGate papers and (if needed) ClinicalTrials.gov identifiers for the relevant trials.
