Northwestern researchers created a wireless brain implant that lets mice interpret artificial signals via light, enabling decision-making without sight, sound, or touch.
A wireless, implantable device developed by Northwestern University researchers uses light to stimulate brain neurons through the skull, enabling mice to interpret artificial signals and make decisions without relying on sight, sound, or touch.
The thin, flexible implant, powered wirelessly and fully beneath the skin, delivers precise light patterns to the brain’s cortex, allowing animals to learn and respond to specific signals in behavioral tasks.
Scientists say the technology marks a major advance in neurobiology and bioelectronics, with potential for restoring lost senses and treating neurological conditions.
The findings, published in Nature Neuroscience, pave the way for future research on complex signal patterns and the brain’s ability to learn artificial neural codes.
