fS is a stand-alone software package designed to process, analyze and visualize functional near infrared (fNIR) spectroscopy signals through a graphical user interface and/or scripting (for auomation). Use fS viewer tools, data management tools, and a scripting engine to view the data in real time and perform post acquisition analysis.with software to view the data in real time and save it for post acquisition analysis.

fNIR is an optical imaging technology that measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (four IR light sources and ten detectors mounted in a flexible band) on the forehead that detects oxygen levels in the prefrontal cortex and provides real-time values for oxy-hemoglobin and deoxygenated hemoglobin. It provides a continuous and real-time display of the oxygen changes as the subject performs different tasks. The fNIR100 System provides 16 channels of information for continuous NIR spectroscopy (NIRS) through 4 light sources and 10 detectors, and includes a control unit, transducer, and software for real-time data viewing and post-acquisition analysis.

 

fNIR analysis data

 

 

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. fNIR is suitable for a wide range of applications, including Human Performance Assessment, Neurorehabilitation, Depth of Anesthesia Monitoring, and Brain Computer Interface.

The fNIR300B stand-alone functional brain imaging system for continuous NIR spectroscopy (NIRS) provides an in-lab cognitive function assessment. It eliminates a great many of the drawbacks of a functional MRI. The subject can sit in front of a computer and take a test or perform mobile tasks. It integrates with stimulus presentation systems and BIOPACs virtual reality products.

Synchronizing the FNIR300B with an MP150 System

The FNIR300B 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 FNIR300B 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.
