FNIR:- FUNCTIONAL NEAR INFRARED IMAGING SYSTEM FOR OXYHB-DEOXYHB MONITORING

An fNIR System provides researchers with real-time monitoring of tissue oxygenation in the brain as subjects take tests, perform tasks, view advertisements, experience ergonomic layouts, or receive stimulation. It allows researchers to quantitatively assess brain functions—such as attention, memory, planning, and problem solving—while individuals perform cognitive tasks. Monitor cognitive state of the subject in natural environments.


About fNIR Technology

Continuous Wave fNIR imaging offers researchers a portable functional near-infrared (fNIR) imaging research tool capable of monitoring brain’s hemodynamics and thereby the cognitive state of the subject in natural environments. fNIR technology employs specific wavelengths in an optical frequency window which can easily pass through a few centimeters for most tissue, and allow monitoring blood oxygenation changes but monitoring back-scattered light intensity. The relative changes of light intensity across time are due to changes in oxy- and deoxy-hemoglobin and provides information about neural activity.fNIR is a powerful near-infrared spectroscopy imaging tool for in-lab cognitive tests and neuromarketing. This technique measures NIR light absorbance in blood of hemoglobin with and without oxygen and provides information about ongoing brain activity similar to functional MRI studies. It eliminates many of the drawbacks of fMRI and provides a safe, affordable, noninvasive solution for cognitive function assessment
