This tiny implant, smaller than a grain of salt, can read your brain

A new neural implant is so small it can rest on a grain of salt, yet it can track and wirelessly transmit brain activity for over a year. It’s powered by laser light that safely passes through tissue and communicates using tiny infrared signals. This ultra-miniature device could transform how scientists study the brain without invasive wiring.
