Depression Affects Working Memory Performance: A Functional Near Infrared Spectroscopy (fNIRS) Study* [PDF]

open access: yesPsychiatry Research: Neuroimaging, 2021
Abstract Depression is a complex disorder that can be caused by psychosocial and biological conditions and it not only effects mood disorders, but also cognitive functions such as memory, decision making, psychomotor speed and attention.

Mental workload classification using convolutional neural networks based on fNIRS-derived prefrontal activity

open access: yesBMC Neurology, 2023
Background Functional near-infrared spectroscopy (fNIRS) is a tool to assess brain activity during cognitive testing. Despite its usefulness, its feasibility in assessing mental workload remains unclear. This study was to investigate the potential use of

Human Discrimination and Categorization of Emotions in Voices: A Functional Near-Infrared Spectroscopy (fNIRS) Study. [PDF]

open access: yesFront 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 ...

The promising fNIRS: Uncovering the function of prefrontal working memory networks based on multi-cognitive tasks

open access: yesFrontiers in Psychiatry, 2022
The diversity of cognitive task paradigms using functional near-infrared spectroscopy (fNIRS) and the lack of theoretical explanations for these functional imaging atlases have greatly hindered the application of fNIRS in psychiatry.

Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa. [PDF]

open access: yesScientific Reports, 2014
AbstractCortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in rural Gambia.

Regulation of cerebral blood flow during stimulus-induced brain activation: Instructions for the correct interpretation of fNIRS signals

open access: yesJournal of Physical Fitness and Sports Medicine, 2014
This review summarizes the regulation of cerebral blood flow (CBF) during stimulus-induced brain activation, mainly in functional near infrared spectroscopy (fNIRS) studies.

NICA: A Novel Toolbox for Near-Infrared Spectroscopy Calculations and Analyses

open access: yesFrontiers 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

Assessment of cerebrovascular dysfunction after traumatic brain injury with fMRI and fNIRS

open access: yesNeuroImage: Clinical, 2020
Traumatic cerebral vascular injury (TCVI) is a frequent, but under-recognized, endophenotype of traumatic brain injury (TBI).  It likely contributes to functional deficits after TBI and TBI-related chronic disability, and represents an attractive target ...
