What was tested?
Neuralink tried an integration that connects its brain chip to xAI's Grok model. Through this system, an ALS patient was able to give commands to a computer using only thought.
The trial ran for 72 hours in the participant's own home, meaning it took place in a daily-life setting rather than a lab.
Why it matters
Brain-computer interfaces (BCIs) translate neural signals into digital commands. Such systems promise communication and control, especially for patients who have lost movement or speech.
