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 ...

You may be surprised to learn that the human brain, often studied under the lens of its electrical and chemical activity, also releases light. It’s a very faint, invisible light that has sparked a ...

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 ...
