Ever-evolving research is steadily turning science fiction into science fact. Neural implants —tiny devices that read or stimulate brain activity —have already entered human trials, showing what’s possible when technology and neuroscience intersect. While early results prove the concept works, the race is now on to make these systems smaller, safer, and more reliable.
Developers and philanthropists alike have ambitious goals: from controlling computers and prosthetics with nothing but thought to restoring movement after paralysis and monitoring neurological disorders in real time.
Now, researchers from Cornell University have taken a major step forward. They’ve created a neural implant smaller than a grain of salt that can wirelessly transmit signals from inside the brain. Their results, published in Nature Electronics, show that this tiny implant emitted clean, uninterrupted data in healthy mice for more than a year.
