Science & TechnologyCornell Team Develops Grain-of-Salt-Sized Wireless Brain Implant
A Cornell University research team has developed a wireless neural implant smaller than a grain of salt that can continuously track and transmit brain activity signals for over a year. Named MOTE and powered by laser light, the device could drive major advances in brain-computer interface technology.
