fNIR Education System
Part #: fNIR103E

fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI.

fNIR optical imaging technology measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources and 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.

Subjects can sit in front of a computer and take a test or perform mobile tasks. fNIR applications include Brain Computer Interface, Human Performance Assessment, Neurorehabilitation, Depth of Anesthesia Monitoring, and more.

fNIR Education Systems for continuous NIR spectroscopy (NIRS) include

  • Imager 2000E control unit (6-optodes max)
  • Sensor and Cable
    • fNIR2000E includes one 6-channel sensor and one sensor cable
  • fNIR Soft and COBl Software
    • Software for data collection and analysis (the included software may change with a 30-day notice; if the included the software changes the existing licensees will receive the replacement software)
  • Lessons (scheduled for release Q1 2020) to record NIRS measurements from the forehead and the forearm at two wavelengths, 730 nm and 850 nm

fNIR Lessons

fNIR Education System lessons* can be used to record NIRS measurements at two wavelengths, 730 nm and 850 nm, with the following objectives:

  • record from the forearm to study changes in Hb and HbO2 during a cuff experiment, to explore the effect of gravity on blood flow, and to investigate hemodynamic changes related to muscle activity.
  • record from the forehead while performing various activities to explore the effects of head movement, blood pressure changes and skin effects on raw intensity measurements and also on Hb, HbO2 and HbT signals.
  • record from the forehead while performing a cognitive test, namely the verbal fluency test, and obtain changes in HbO2 and Hb under different conditions within this cognitive test.
  • record from the forehead while performing a test of different cognitive loads manipulated as single and dual task conditions.

*Lessons scheduled for Q1 2020.

Imager 2000E Specs

  • Max Sources: 2
  • Max Detectors: 6
  • Max Sampling Frequency: 2 Hz
  • Wireless: no
  • Synchronization ports: no
  • Dimensions: 106 mm x 32 mm x 106 mm

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 (ERP) and ensemble averaging. Combining the fNIR data with other physiological signals provides researchers with a detailed subject assessment.

fNIRSoft (fS) Software & COBI Studio

fS is a software package for use with the 2000E Imager for Education Systems. Use fS viewer and data management tools to process, analyze, and visualize functional near infrared (fNIR) spectroscopy signals. View data in real time and perform post-acquisition analysis.

COBI Studio “Cognitive Optical Brain Imaging” software is designed for performing serial experiments and makes it easy to start recording, and to save all experimental data (fNIR, synchronization markers from external presentation stimuli, etc.) in a standardized way.


For additional details, review these items under the Support tab:

  • fNIR and COBI Studio User Guide for data collection guidelines
  • fNIRSOFT User Manual for a step-by-step guide for using fS, with an introduction to fNIR technology and a discussion of the Modified Beer Lambert Law (MBLL) that is integral to the analysis of fNIR spectroscopy signals
