brain-computer interface

Brain-computer interfaces convert neural signals into digital commands. From Vidal's 1973 coinage to Neuralink's 2024 human implant, here's how BCIs work and what they can and cannot do.

Inside Neuralink's N1 implant — 1024 electrodes, a surgical robot, and the race to give paralyzed patients control of computers with thought alone.

Brain-computer interfaces are already decoding thoughts into words. What happens when the technology scales — and who gets to see what you're thinking?

AI-powered BCIs are restoring cursor control, handwriting, and speech to people with paralysis. Here is how the decoding works and where it still fails.

Mind uploading — copying your conscious self into a computer — is a staple of science fiction. The science is fascinating, the obstacles enormous, and the philosophy genuinely confusing.

A device implanted in the brain that lets paralysed patients move computer cursors with their thoughts. Here's how Neuralink and other brain-computer interfaces actually work.
