Noland Arbaugh, the first human to receive Elon Musk’s Neuralink N1 brain implant, has shared a detailed update after completing 100 days with the device embedded in his brain. Arbaugh, who has been paralyzed from the shoulders down since a 2016 diving accident, described the experience as “science fiction that somehow became my everyday reality.”
As reported by Neuralink in their official update, the patient underwent surgery at Barrow Neurological Institute in Phoenix, Arizona, where a robotic system placed 1,024 ultra-thin threads into his motor cortex through a small incision.
The 30-year-old Arizona resident was discharged the day after surgery and within three days reported feeling “much better.” According to what Scientific American noted in their coverage, Arbaugh says he “wouldn’t know the hardware was there” unless he remembered the surgery, as there is no physical sensation of the implant unless touched directly. By week two, he had paired the device with a MacBook and within minutes was moving a cursor simply by thinking, describing the initial sensation as “like trying to remember a dream.”
Neuralink Brain Chip Enables Gaming and Full Digital Independence
The transformation in Arbaugh’s daily life has been substantial. Before the implant, he relied on voice commands and a mouth-held stylus to control computers, which required constant caregiver assistance and caused discomfort, muscle fatigue, and pressure sores.
As reported by Times of India, by week three after implantation, scrolling, clicking, and typing had become “second nature” for the patient, who went from being a complete Mac novice to what he describes as a “power-user” in record time.
Perhaps most remarkable is Arbaugh’s return to gaming. Around day 80, he began playing World of Warcraft completely hands-free. While the first raid felt “clunky,” he reports that after his brain and the BCI synchronized, the experience became “pure magic.” “I’m now raiding and exploring Azeroth at full speed—no mouse, no keyboard, just intention,” Arbaugh stated, calling the freedom “addictive.” The official Neuralink data shows that his usage averaged 8 hours per day during weekdays and exceeded 10 hours daily on weekends, with one week reaching a total of 69 hours of device usage.
In terms of technical performance, Arbaugh set a world record of 4.6 bits per second (BPS) in his first session and has since improved to 8.0 BPS, approaching the approximately 10 BPS that able-bodied individuals achieve with a traditional mouse.
Technical Challenges and the Future of Brain-Computer Interfaces
Approximately one month after surgery, about 85% of the implant threads retracted from their original position in the brain, causing a significant reduction in effective electrodes. This initially decreased performance, but Neuralink engineers responded by modifying the recording algorithm sensitivity and improving the signal-to-cursor-movement translation techniques. These adjustments not only restored functionality but ultimately exceeded the original performance metrics.
For future patients, Neuralink has adjusted its protocol. The second patient received a deeper implantation—8mm compared to Arbaugh’s 3-5mm—to address the thread retraction issue. Arbaugh maintains a philosophical perspective about his role as a pioneer: “The whole point of this study was to find out what does and doesn’t work. I’m happy to be among the first, and I’m excited for the next person to get something even better.”
“100 days in and I already can’t imagine life without it. The N1 didn’t just give me a new way to use a computer—it gave me a new way to live,” Arbaugh concluded in his update. While Neuralink’s brain implant remains in its clinical trial phase, Arbaugh’s testimony provides a compelling glimpse into how brain-computer interfaces could fundamentally reshape independence for the estimated 180,000 Americans currently living with quadriplegia, and the approximately 18,000 who suffer new spinal cord injuries each year.
