Area of Science:

Neuroimaging
Biomedical Engineering
Cognitive Neuroscience

Background:

Functional near-infrared spectroscopy (fNIRS) is a noninvasive neuroimaging technique measuring cerebral blood volume and oxygenation using near-infrared light.
Its portability, lower cost, and versatility make fNIRS suitable for pediatric populations and studies outside traditional laboratory settings, unlike fMRI.
Analyzing fNIRS data presents unique challenges due to its physics, data properties, and diverse experimental designs.

Purpose of the Study:

Introduce the NIRS Brain AnalyzIR toolbox, an open-source Matlab package.
Provide a comprehensive solution for fNIRS data management, pre-processing, and statistical analysis.
Address the analytical challenges inherent in fNIRS data.

Main Methods:

Developed an open-source Matlab-based toolbox named NIRS Brain AnalyzIR.
Utilized an object-oriented programming paradigm for the toolbox architecture.
Implemented algorithms for statistical analysis, probe registration, image reconstruction, and ROI-based statistics.

Main Results:

The NIRS Brain AnalyzIR toolbox facilitates data management, pre-processing, and statistical analysis for fNIRS studies.
The toolbox supports both single-subject (first-level) and group-level (second-level) analyses.
Detailed algorithms for key components ensure robust data processing and analysis.

Conclusions:

The NIRS Brain AnalyzIR toolbox provides a necessary and specific analysis solution for fNIRS data.
Its open-source nature and comprehensive features support the growing use of fNIRS in neuroscience research.
The toolbox aims to overcome the analytical hurdles associated with fNIRS data, enhancing its utility.
