Elon Musk’s brain-machine interface company Neuralink showcased a pig outfitted with the company’s device, at an event livestreamed on YouTube. One pig, Gertrude, had a device recording signals from an area of the brain linked to her snout. She’d had the implant for two months at the time of the demonstration.
The design of the Neuralink device has changed since it was unveiled last year, rendering the device itself hard to see on Gertrude. It is now coin-shaped, and meant to sit flush with the skull, rather than having a small module resting near the ear. It’s “like a Fitbit in your skull with tiny wires,” Musk said. The device can pair with a smartphone app over Bluetooth Low Energy, he said.
