fNIRS

Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive imaging technique that measures brain activity by detecting changes in blood oxygen levels. It uses safe, near-infrared light shined through the skull into the brain, and sensors pick up how much light is absorbed. Active brain areas consume more oxygen, altering blood flow and oxygenation in those regions. By analyzing these signals, fNIRS provides real-time information about brain function, helping researchers and clinicians understand how different parts of the brain respond during various tasks or conditions.
