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 ...

In a discovery that sounds like science fiction, researchers have shown that human brains emit flashes of light that can pass through the skull. These signals are so tiny and faint that they're a ...

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 small team of brain researchers at South China Normal University, working with a colleague from the University of New South Wales, has found that the visual processing parts of the brain light up in ...

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 ...
