Functional near-infrared spectroscopy
IEEE Engineering in Medicine and Biology Magazine, 2006The purpose of the this article is to describe an emerging neuroimaging technology, functional near-infrared spectroscopy (fNIRs), which has several attributes that make it possible to conduct neuroimaging studies of the cortex in clinical offices and under more realistic, ecologically valid parameters.

Cerebrovascular Reactivity Measurement with Functional Near Infrared Spectroscopy
Journal of Visualized Experiments, 2022Cerebrovascular reactivity (CVR) is the capacity of blood vessels in the brain to alter cerebral blood flow (either with dilation or constriction) in response to chemical or physical stimuli. The amount of reactivity in the cerebral microvasculature depends on the integrity of the capacitance vasculature and is the primary function of endothelial cells.

Transformer Model for Functional Near-Infrared Spectroscopy Classification
IEEE Journal of Biomedical and Health Informatics, 2022Functional near-infrared spectroscopy (fNIRS) is a promising neuroimaging technology. The fNIRS classification problem has always been the focus of the brain-computer interface (BCI). Inspired by the success of Transformer based on self-attention mechanism in the fields of natural language processing and computer vision, we propose an fNIRS ...

Superficial Fluctuations in Functional Near-Infrared Spectroscopy
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019Functional near-infrared spectroscopy (fNIRS) is a non-invasive optical functional neuroimaging that has seen rapid development and increasing use in studying human brain under normal and diseased conditions. Compared with blood-oxygenation-level dependent functional magnetic resonance imaging (BOLD fMRI), fNIRS offers advantages including its low cost,

Resting state functional near infrared spectroscopy
2013 Pan American Health Care Exchanges (PAHCE), 2013The present study investigated the spatial-temporal variation of oxygenated hemoglobin (HbO), deoxygenated hemoglobin (Hb), blood volume (BV) and blood oxygenation (BO) concentration changes in the prefrontal cortex, measured with functional near-infrared spectroscopy (fNIRS) during resting state.

Conducting Hyperscanning Experiments with Functional Near-Infrared Spectroscopy
Journal of Visualized Experiments, 2019Concurrent brain recordings of two or more interacting persons, an approach termed hyperscanning, are gaining increasing importance for our understanding of the neurobiological underpinnings of social interactions, and possibly interpersonal relationships.

Speaking mode recognition from functional Near Infrared Spectroscopy
2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012Speech is our most natural form of communication and even though functional Near Infrared Spectroscopy (fNIRS) is an increasingly popular modality for Brain Computer Interfaces (BCIs), there are, to the best of our knowledge, no previous studies on speech related tasks in fNIRS-based BCI.

Functional near infrared spectroscopy (fNIRS)
2020Functional near infrared spectroscopy (fNIRS) provides an essential bridge between our knowledge of adult human brain function and our current understanding of the developing brain. The capacity for fNIRS to provide localized measures of functional activation within awake and mobile infants, combined with a low set-up time and high tolerance to ...
