The Brite has been proven to be the best and most advanced wearable fNIRS device on the market. Through this potential, we set the Brite as the standard multi-channel wearable fNIRS system. Consequently, the Brite Lite serves as a wireless & flexible 10-channel fNIRS device for brain oxygenation measurements and the Brite Lite Frontal is optimized for measuring prefrontal cortical activation in the brain with 8 fNIRS channels.
