A Vancouver police sergeant living with amyotrophic lateral sclerosis has become one of the first Canadians to receive a brain implant made by Neuralink, the neurotechnology company owned by Elon Musk, in a procedure that doctors are describing as a significant medical milestone. Lee Marten, a 48-year-old officer known for his bike patrols and his charity work, underwent the experimental surgery at a Toronto hospital and was able to move a computer cursor with his thoughts within about an hour of the operation. For Marten, whose disease is slowly stripping away his ability to move and, eventually, to speak, the implant represents a bet on technology to preserve what he can still do. His case has drawn national attention as one of the earliest of its kind performed in Canada.
The surgery took place at the University Health Network's Toronto Western Hospital, where a neurosurgery team led by Dr. Andres Lozano carried out the delicate procedure in May. Marten qualified for the clinical trial over a video call and became the 26th person in the world to receive a Neuralink device. The hospital had already implanted the technology in two Canadian patients with spinal cord injuries the previous summer, but Marten's operation carried an added significance. It was, according to the team, the first time the device had been placed in a patient through a new and less invasive route.
That distinction lies in how the electrodes were inserted. In earlier Neuralink surgeries, human surgeons first peeled back the dura, the tough protective membrane surrounding the brain, before a robot threaded the electrodes into the tissue beneath. In Marten's case, the robot worked directly through the intact dura for the very first time, threading more than a thousand electrodes, each thinner than a human hair, into the brain's motor cortex without the need to cut the membrane away. Doctors described it as a step toward making the operation simpler, safer and easier to offer to far more people in the years ahead.
The technology itself is designed to translate thought into action. Once implanted, the electrodes pick up signals from the motor cortex and send them, by way of the same Bluetooth used for wireless speakers, to a computer, allowing a patient to move a cursor or type using only their intentions. The stated goal of the trial is to help people who have lost the ability to move or speak to communicate again, and eventually to control robotic limbs. Marten reportedly began controlling the cursor within an hour of surgery, the fastest of any participant so far, and woke in intensive care with 27 staples in his scalp.
For Marten and his family, the appeal of the implant is intensely personal. ALS is a progressive disease that destroys nerve cells in the brain and spinal cord, and there is no cure; over time he is expected to lose the ability to speak, eat and breathe. His wife, Lisa, first heard about the Neuralink trial through an advertisement and signed him up without hesitation, viewing it as a last option. One of the family's greatest hopes is that the device will allow Marten to keep communicating with his young daughter even after his voice is gone, and to make his own wishes clear on the difficult medical decisions that may lie ahead.
The trial has not been without controversy. Some doctors have objected to a Canadian public hospital partnering with a company owned by Musk, citing his role in cutting American funding to global health programs, while critics have accused Neuralink of a lack of openness, arguing that much of its publicly available information reads more like marketing than detailed scientific analysis. Toronto Western has defended its participation, saying the decision was made in the best interests of patients and of science and that the project passed a series of ethical reviews. The debate reflects the unusual position of cutting-edge medical research tied to one of the world's most polarizing figures.
In the weeks since the operation, Marten has tried to turn his diagnosis into a form of advocacy. Still healing, he took in a baseball game and visited the Hockey Hall of Fame, and on a whim had the words patient 26 tattooed on his body. He has since served as an ambassador at a fundraising walk for ALS research, casting his participation in the trial as a way to help others facing the same disease. He has even been able to keep working, carrying out follow-up tasks for Neuralink's engineers that he says help keep him busy. For a man confronting an incurable illness, the implant has become both a practical tool and a source of meaning.
