Neuralink, the brain technology startup founded by Elon Musk, made headlines recently with the successful implantation of its brain chip in the first human participant, Noland Arbaugh. The groundbreaking scientific research paves the way for improving the lives of paralyzed people.
Arbaugh became a quadriplegic after sustaining a spinal cord injury from a diving accident eight years ago. In January 2024, he underwent surgery to receive Neuralink's brain implant chip, which is approximately the size of a coin and implanted beneath the skull.
The device uses 64 tiny wires equipped with over 1,000 electrodes to read neuron activity in the brain and connect with a computer or smartphone. Arbaugh can now have nearly full control over using a computer just by thinking, something he was not able to do before the implant.
Neuralink plans to implant two new study participants in the coming months, aiming to help people who cannot use their arms control computers and tablets using their thoughts. The company also plans to test a robotic arm that could be controlled by thought and used for tasks like controlling a smart home or operating a prosthetic arm.
Despite some initial issues with the technology, Neuralink made modifications to improve Arbaugh's connection and restore lost data. He is now hopeful that spinal cord injuries will not be completely debilitating in the future.
Neuralink was co-founded by Elon Musk in 2016 and is one of several companies testing brain-computer interfaces in volunteers with paralysis. These devices can decode brain signals, allowing people to control external devices using their thoughts.
Arbaugh's interview on Good Morning America provided a firsthand account of his experience with the Neuralink technology and its impact on his life.
