Quality control and assurance in functional near infrared spectroscopy (fNIRS) experimentation [PDF]
Physics in Medicine and Biology, 2010 Functional near infrared spectroscopy (fNIRS) is a rapidly developing neuroimaging modality for exploring cortical brain behaviour. Despite recent advances, the quality of fNIRS experimentation may be compromised in several ways: firstly, by altering the optical properties of the tissues encountered in the path of light; secondly, through adulteration ...

Measurement of Brain Function of Car Driver Using Functional Near‐Infrared Spectroscopy (fNIRS) [PDF]
Computational Intelligence and Neuroscience, 2009 The aim of this study is to propose a method for analyzing measured signal obtained from functional Near‐Infrared Spectroscopy (fNIRS), which is applicable for neuroimaging studies for car drivers. We developed a signal processing method by multiresolution analysis (MRA) based on discrete wavelet transform.

Human Discrimination and Categorization of Emotions in Voices: A Functional Near-Infrared Spectroscopy (fNIRS) Study. [PDF]
Front Neurosci, 2020 Abstract Variations of the vocal tone of the voice during speech production, known as prosody, provide information about the emotional state of the speaker. In recent years, functional imaging has suggested a role of both right and left inferior frontal cortices in attentive decoding and cognitive evaluation of emotional cues in human ...

NICA: A Novel Toolbox for Near-Infrared Spectroscopy Calculations and Analyses
Frontiers in Neuroinformatics, 2020 Functional near-infrared spectroscopy (fNIRS) measures the functional activity of the cerebral cortex. The concentration changes of oxygenated (oxy-Hb) and deoxygenated hemoglobin (deoxy-Hb) can be detected and associated with activation of the cortex in
