In 2024, Elon Musk’s Neuralink put its first brain implant into a human amid doubt from scientists and allegations of animal cruelty.
Two and a half years later, that first patient is one of more than 20 “neuralnauts” who use their implants to participate in the online world.
Brain implants are becoming smaller, more compatible with human bodies, and dramatically more capable. People with paralysis can use brain-computer interfaces to produce speech almost instantaneously.
Earlier this year, researchers in the United Kingdom showed volunteers wearing a headset could control robotic limbs and their natural ones at the same time.
As the industry takes off, we will see more and more clinical trials of devices that are implanted in the brain.
In a recent study, my colleagues and I tried to address an increasingly important question: when a clinical trial of an experimental neural device ends, what does that mean for the human participants?
