Several companies are testing brain implants – why is there so much attention swirling around Neuralink? Two professors unpack the ethical issues


Brain-computer interface devices have the potential to boost users’ autonomy, especially for people who experience paralysis. But that comes with risks, as well.

Subjects in the company’s PRIME study – short for Precise Robotically Implanted Brain-Computer Interface – undergo surgery to place the device in a part of the brain that controls movement. However, the N1 implant combines more technologies in a single device: It can target individual neurons, record from thousands of sites in the brain and recharge its small battery wirelessly. This raises thorny questions about whether it is ever ethical to provide early access to breakthrough medical interventions prior to their receiving full FDA approval.
