SO YOU WANT TO REWIRE BRAINS

There's a lot to like about brain-computer interfaces, those sci-fi-sounding devices that jack into your skull and turn neural signals into software commands. Experimental BCIS help paralyzed people communicate, use the internet, and move prosthetic limbs.

In recent years, the devices have even gone wireless. If mind-reading computers become part of everyday life, we'll need doctors to install the tiny electrodes and transmitters that make them work. So if you have steady hands and don't mind a little blood, being a BCI surgeon might be a job for you. Shahram Majidi, a neurosurgeon at Mount Sinai Hospital in New York, began operating in clinical trials for a BCI called the Stentrode in 2022. (That's "stent" as in a tube that often sits inside a vein or artery.) Here he talks about a not-too-distant future where he's performing hundreds of similar procedures a year.
