NIRS can be used on infants, and NIRS is much more portable than fMRI machines, even wireless instrumentation is available, which enables investigations in freely moving subjects. [23] [24] However, NIRS cannot fully replace fMRI because it can only be used to scan cortical tissue, whereas fMRI can be used to measure activation throughout the ...

Near-infrared spectroscopy, a spectroscopic method that uses the near-infrared region (from 780 nm to 2500 nm). National Identity Register, a former UK database; National Internet registry, which coordinates IP address and other resource allocation; NIR, proposed variation of the SECAM colour television system in the Soviet Union
Diffuse optical imaging (DOI) is a method of imaging using near-infrared spectroscopy (NIRS) [1] or fluorescence-based methods. [2] When used to create 3D volumetric models of the imaged material DOI is referred to as diffuse optical tomography , whereas 2D imaging methods are classified as diffuse optical imaging .
This toolbox is a set of Matlab-based tools for the analysis of functional near-infrared spectroscopy (fNIRS). This toolbox defines the +nirs namespace and includes a series of tools for signal processing, display, and statistics of fNIRS data. This toolbox is built around an object-oriented framework of Matlab classes and namespaces. [18]
In general, the goal of absorption spectroscopy is to measure how well a sample absorbs or transmits light at each different wavelength. Although absorption spectroscopy and emission spectroscopy are different in principle, they are closely related in practice; any technique for emission spectroscopy can also be used for absorption spectroscopy.
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
