Recently, Semafor received an extraordinary iMessage. It was from Rodney Gorham, a paralyzed ALS patient, and he had sent it directly from his brain. Gorham has a brain implant called Stentrode. Unlike previous generations of brain-computer interfaces, the Stentrode, from the neurotechnology company Synchron, can be implanted without invasive brain surgery. But… what *are* brain-computer interfaces? How do they work? And where is this novel technology going?
