fNIR is an optical imaging technology that measures neural activity and hemodynamic response in the prefrontal cortex. The subject wears a sensor on the forehead that includes an IR light source and two detectors that are mounted in a flexible band. The fNIR sensor detects the oxygen levels in the prefrontal cortex and provides values for oxy-hemoglobin and deoxygenated hemoglobin in real time. It provides a continuous and real-time display of the oxygen changes as the subject performs different tasks, and is comfortable to wear for prolonged periods of time.
 
 
The wireless fNIR200-W provides users with an in-lab or ambulatory assessment of cognitive function. It eliminates a great many of the drawbacks of a functional MRI. The subject can move freely in real-world situations, or sit in front of a computer and take a test or perform mobile tasks. It integrates with stimulus presentation systems and BIOPAC’s virtual reality products. The fNIR data combines with other physiological variables 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. Combining the fNIR data with the other physiological signals provides researchers with a detailed subject assessment.

fNIR200-W is suitable for a wide range of applications: Human Performance Assessment, Depth of Anesthesia Monitoring, Brain Computer Interface, Virtual Reality, Neurorehabilitation, Autism, and Credibility Assessment (lie detection).

SYNCHRONIZING FNIR200-W WITH AN MP150 SYSTEM

The fNIR control device has a BNC trigger output that sends TTL pulses at the beginning and end of baseline, and at the beginning and end of a recording session. The trigger can be used to start the MP150 for data collection and to record the start and end of each fNIR segment.

TRIGGER ACQUISITION AND RECORD DIGITAL TRIGGERS

Connect a BNC to BNC cable between the FNIR control device BNC trigger and the Isolated Digital Interface Module (STP100C), External Trigger port, and set AcqKnowledge to External trigger. To record the triggers, connect a Jumper Cable (JUMP100) between the TRIG and one of the Digital I/O lines on the rear of the Universal Interface Module (UIM100C). Turn on the digital I/O line and the system will record and display the triggers on the digital channel.
