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.
fNIRSoft (fS) Standard Edition Software
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.
Optional upgrade to fS Pro Edition extends functionality with these additional tools not provided in fS Standard:
- fS Signal Analysis: Data Processing Tools
- fS Viewer: Temporal Visualization, Time Series Analysis Tools
- fS Viewer: Topograph Tools – including brain mapping and visualization over brain surface image
Use fNIR Systems with an MP160 Research System
Synchronize
With the optional BNC connector the Imager 2000C control device can send 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 MP160 for data collection and to record the start and end of each fNIR segment.
Trigger Acquisition
Connect a BNC to BNC cable between the Imager 200S control device BNC trigger and the Isolated Digital Interface Module (STP100C), External Trigger port, and set AcqKnowledge to External trigger.
Record Digital Triggers
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.
