According to a written statement on Neuralink's website, the amount of data received by the processor and battery in the skull from the nerves decreased due to the retraction of 64 connection cables implanted in Noland Arbaugh's brain tissue.

The company stated that the decrease in the amount of data processed by pulling back the cables does not pose a danger to the health of Arbaugh, the first brain chip user, and noted that studies are continuing to increase the functionality of the device.

Arbaugh, who had the chip implanted in his brain on January 28, was only able to play chess by thinking in the weeks following the surgery. Neuralink announced in late February that the chip was capturing less data.

Arbaugh, whose hands and feet were left paralyzed after an accident about 8 years ago, played chess using the chip despite the problem in a live broadcast on his X account on May 4.
