Measure oxygen level changes in the prefrontal cortex of human subjects.
Eliminates many of the drawbacks of fMRI
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.
Easily sync with stimuli presentation systems and integrate with other physiological and neurobehavioral measures that assess human brain activity, including eye tracking, pupil reflex, respiration, and electrodermal activity.

Continuous Wave fNIRS 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. fNIRS 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.

fNIRS Neuroimaging Solution for Natural Environments
fNIRS 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. The technology empowers researchers by providing greater flexibility for study design, including working within complex lab environments and operating in non-traditional lab locations for field studies (neuromarketing). The fNIR device provides relative change in hemoglobin levels, calculated using a modified Beer-Lambert law.
fNIR data combines with physiological signals acquired through BIOPACs data acquisition and analysis systems such as ECG, respiration, cardiac output, blood pressure, electrodermal activity and stimulus response markers; AcqKnowledge® software provides automated analysis tools for event related potentials and ensemble averaging. The system interfaces with most stimulus presentation systems (such as E-Prime or SuperLab) and BIOPAC’s range of Virtual Reality systems.
