This time last year, Noland Arbaugh became the first human patient to receive a brain implant from Neuralink, Elon Musk’s neurotechnology startup. In the following months, two more patients have been implanted with Neuralink devices, according to the company. “They’re all working well,” Musk said of the three implants last week during a live streamed interview on X. Neuralink, which uses a surgical robot to implant its N1 brain-computer interface (BCI) into human brains, expects to perform 20 to 30 implants in patients this year, Musk added.
