Noland Arbaugh, a quadriplegic, is the first person to receive a Neuralink brain implant.
The brain-computer interface (BCI) translates brain signals into digital commands.
Arbaugh can now browse the Internet, send messages, and play video games using only his mind from his home in Yuma, Arizona.
The implant detects electrical signals in the brain.
Experts cite privacy concerns regarding access to brain activity.
Arbaugh hopes for future advancements enabling control of wheelchairs or humanoid robots.
