FDA reportedly denied Neuralink's request to begin human trials of its brain implant

Despite the repeated and audacious claims by its sometimes CEO, Elon Musk, the prospects of brain-computer interface (BCI) startup Neuralink bringing a product to market remain distant, according to a new report from Reuters. The BCI company was apparently denied authorization by the FDA in 2022 to conduct human trials using the same devices that killed all those pigs — namely on account of; pig killing.

"The agency’s major safety concerns involved the device’s lithium battery; the potential for the implant’s tiny wires to migrate to other areas of the brain; and questions over whether and how the device can be removed without damaging brain tissue," current and former Neuralink employees told Reuters.
