Neuralink's first human patient reports device failure and privacy loss

What happened

Noland Arbaugh, a 30-year-old paralyzed since a diving accident in 2016, received a Neuralink brain implant in January 2024 and became the first human to do so. The 23-millimeter device with 1,024 electrodes was implanted via surgical robot to detect motor signals and transmit wireless commands to external devices.

The device initially allowed Arbaugh to control a computer cursor with his thoughts and perform activities including writing, web browsing, and playing video games. However, the device experienced a technical failure that caused him to lose control of his computer, generating significant distress until Neuralink engineers adjusted the software to restore and improve the connection.

Reported impact

Arbaugh reported regaining independence and autonomy to perform tasks he believed lost after his accident. He stated he could compete with friends in digital games, an activity he had to abandon after paralysis.

Arbaugh disclosed that he 'lost all privacy, all independence' and described the emotional toll of accepting complete dependence on others for all daily needs. Experts have warned that access to brain activity data could compromise personal information.

Index analysis

The incident illustrates risks in early-stage neurotechnology deployment, including system reliability failures with psychological consequences for users whose autonomy depends on device function. Experts identified privacy risks from brain activity data access as a concern requiring safeguards.
