Scientists have built a soft, wireless Implant that lets the brain interpret patterned light as if it were a new kind of touch, turning beams into information the cortex can actually use. Instead of ...

Restoring lost senses or delivering precise brain signals has required invasive hardware and can’t mimic the brain’s natural, distributed activity patterns. This platform shows the brain can learn to ...

For decades, scientists have used near-infrared light to study the brain in a noninvasive way. This optical technique, known as fNIRS (functional near-infrared spectroscopy), measures how light is ...

A new brain-machine interface (BMI) uses light to "speak" to the brain, mouse experiments show. The minimally invasive wireless device, which is placed under the scalp, receives inputs in the form of ...

The thin, flexible, wireless device sits next to a quarter for scale. Device emits complex patterns of light (shown here as an "N") to transmit information directly to the brain. In a new leap for ...
