Scientists are developing brain implants that let people move a cursor, text a friend, or even control a device—just by thinking.

Neuralink, Paradromics, Synchron and others are already testing chips that restore movement, speech, and even vision for people with paralysis, epilepsy, and other neurological conditions. Some implants don’t even require brain surgery—just a blood vessel.

These aren't science fiction prototypes—they're in human trials now.

The brain is talking. And for the first time, the world is starting to listen.
