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 ...

Light is quietly becoming the new language of brain technology. Instead of thick wires and skull-penetrating electrodes, a new generation of implants uses tiny LEDs and optical sensors to send ...

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 ...

The researchers also ran detailed computer simulations to predict how light would move through the complex layers of the head. These simulations matched the experimental results closely, confirming ...

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 ...
